Breed Composition Codes for Crossbred Dairy Cattle in the United States
Crossbreds are animals whose genes are derived from more than one breed, such as a cow with a Holstein sire and a Jersey dam. A system for storing breed composition data for US dairy cattle has been developed and the necessary software implemented. This system is necessary to facilitate implementation of an across-breed genetic evaluation. Crossbred animals in the US dairy cattle population do not currently receive genetic evaluations. Two ways that crossbred animals may be handled in an evaluation are: they may be included in the breed-of-sire evaluation, or all animals may be combined into a single evaluation. For each crossbred cow (n=246,218) the database stores animal identification, breed of animal registry, breed fractions for 18 dairy breeds and an “unknown” category, a four-generation breed stack, a sire breed stack, and a heterosis value. Standard two-letter breed codes are used in the breed stacks. Breed fractions were calculated from pedigree information in the USDA database as far back as data were available.
Lesson 9 Law of independent assortment.Dihybrids
This document summarizes a lesson on dihybrid crosses involving two genes: pod color (G/g) and pea color (Y/y).
- The possible genotypes and phenotypes for each trait are outlined.
- A Punnett square is used to show the cross and genotypes of the F1 generation between plants with green pods/yellow peas and yellow pods/green peas. The F1 are all heterozygous (GgYy) and have the phenotype of green pods and yellow peas.
- Another Punnett square shows the cross between two F1 plants, predicting the possible genotypes and phenotypes of the F2 generation based on the law of independent assortment.
Punnett squares
Punnett squares can be used to predict the possible genotypes and phenotypes of offspring from a genetic cross between two parents. Mendel performed dihybrid crosses involving two traits, like seed shape and color, and found independent assortment of traits in a 9:3:3:1 ratio. A Punnett square represents the possible combinations of alleles from each parent that are passed on to offspring. It accurately predicts the probability but not absolute outcomes of genetic crosses.
Genetic experiment on the offspring of drosophila melanogaster
1) The experiment aimed to determine if mating Drosophila melanogaster in a dihybrid cross would yield results similar to Mendel's 9:3:3:1 ratio by observing inheritance of eye color (red vs white) and body color (ebony vs brown).
2) The F1 generation showed more dominant traits than recessive, but not all were dominant as in Mendel's experiments. The F2 results using a chi-square test did not match the expected 9:3:3:1 ratio.
3) Errors were made in transferring flies between generations that may have impacted the results, which were ultimately deemed inconclusive. Proper fly handling and food preparation are needed to obtain clear results.
Alien Genetics Problems
The document describes the traits and genetics of an alien species, including body color, number of antennae, eye color, eyesight, and number of body rings. A chart provides the dominant and recessive phenotypes for each trait. Several genetics problems then ask the reader to determine the chances of particular outcomes when aliens with specified traits mate and have offspring.
Essential Biology 6.6 & 11.1 Reproduction Core & AHL
The document provides a series of questions related to human reproduction and biology. It begins by listing keywords and websites for further research. It then provides over 50 questions spanning topics such as gamete formation, the structure and function of reproductive systems, hormonal control of the menstrual cycle and pregnancy, embryonic development, childbirth, and variations in human traits. The questions employ various cognitive levels including define, label, outline, compare, explain, evaluate, and discuss. Sources are to be cited using the CSE citation style.
Green Book 9
1) Gregor Mendel conducted experiments with pea plants to study inheritance of traits and discovered that traits are passed from parents to offspring via discrete units called genes.
2) Through monohybrid crosses between true-breeding pea plants with contrasting traits, Mendel observed that one trait would disappear in the F1 generation but reappear in the F2 generation, suggesting that genes do not blend during inheritance.
3) Analysis of the ratios of traits in subsequent generations provided numerical evidence that genes segregate into gametes independently during reproduction, allowing for dominant and recessive traits.

This type of deafness in the teacher is unlikely to be inherited by their new baby because:
- The teacher developed deafness as a result of environmental factors (noisy classes), not genetic factors. Their deafness was acquired and not something they were born with.
- Acquired or environmental traits are not heritable as they are not encoded in our genes. They result from interactions with the surrounding environment rather than our genetic makeup.
- For a trait to be inherited, it must have a genetic basis - the trait must be influenced by the genes we receive from our parents. Since the teacher's deafness was caused by environmental noise exposure rather than a genetic mutation or condition, it would not be passed on to offspring through their
Bio22 4th post lab discussion
This document summarizes key stages in embryonic development:
1) Fertilization, cleavage, gastrulation, neurulation and organogenesis are the main developmental stages described.
2) During cleavage, the fertilized egg undergoes rapid cell divisions without growth. Gastrulation involves the invagination and involution of cells to form the three germ layers.
3) Neurulation involves the formation of the neural plate which curves inward to form the neural tube from ectoderm. Mesoderm forms blocks called somites during development.

This document summarizes a study that found the transcription factors eyes absent (eya) and sine oculis (so), which are involved in eye development, are also required in the somatic cyst cells of the Drosophila testis for proper spermatocyte development. The study found that eya mutant testes exhibit degenerating young spermatocytes, and mosaic analysis revealed a somatic requirement for both eya and so in the cyst cells, not in the germline. Immunolocalization showed eya and so proteins are expressed in cyst cell nuclei as spermatocytes differentiate. The study suggests eya and so may form a transcription complex in the cyst cells to activate genes involved in cyst cell differentiation and s

General embryology - Copy.pdf
Embryology is the study of prenatal human development from fertilization to birth. It involves the formation and differentiation of gametes through meiosis, fertilization, cleavage and formation of the blastocyst. The blastocyst then implants in the uterus and undergoes differentiation into the three germ layers through gastrulation and neurulation. The developing human is termed an embryo from fertilization to 8 weeks, and then a fetus from 8 weeks until birth. Embryology provides insights into normal and abnormal human development, anatomy and congenital defects.

This document discusses two main types of bonding: ionic bonding and covalent bonding. Ionic bonding involves the transfer of electrons from metal atoms to non-metal atoms, resulting in positively charged metal ions and negatively charged non-metal ions that are attracted to each other. Covalent bonding involves the sharing of electron pairs between non-metal atoms to form stable molecular structures. Examples of ionic compounds include sodium chloride and magnesium chloride, while examples of covalent compounds discussed are hydrogen gas, ammonia, and water.

The document provides a key for scientists to identify different types of plastics based on their properties when heated or burned. The key involves a series of yes/no questions to determine if the plastic melts with heat, burns, drips when burned, smells fishy or cracks when heated, and whether it continues burning after the flame is removed. Plastic A is identified as rigid PVC as it smells fishy when heated but does not crack or drip. Plastic B is identified as polystyrene as it melts with heat and continues burning after the flame is removed. The key helps determine the type of plastic through a process of elimination based on its observable properties when exposed to heat or fire.
