Genetics is the study of heredity and genes. Gregor Mendel conducted experiments with pea plants in the 1800s that formed the basis of genetics. Through his work, he discovered the principles of inheritance, including that traits are determined by units now called genes, genes occur in different forms called alleles, dominant alleles mask recessive alleles, and alleles assort independently during gamete formation. Mendel's principles can be used to predict the results of genetic crosses and the inheritance of traits.

Genetic linkage
Morgan conducted experiments in Drosophila melanogaster that discovered genetic linkage. He crossed a white-eyed, miniature-winged female to a wild-type male. In the F2 generation, most flies showed the parental phenotypes of white eyes and miniature wings, or wild-type eyes and wings. However, some flies showed non-parental phenotypes of white eyes and normal wings, or wild-type eyes and miniature wings, demonstrating genetic recombination between the two linked genes. This provided evidence that genes on the same chromosome may assort together during meiosis but can also undergo crossing over, resulting in new combinations of alleles. Morgan's discovery established the chromosomal theory of inheritance and allowed the field of genetics to construct genetic maps

This document summarizes an experiment using Mendelian genetics to study the inheritance of traits in Drosophila melanogaster (fruit flies). Two mutant fly strains, 27D with brown eyes and 27E with vestigial wings, were crossed with a wild-type strain to observe phenotypic ratios over multiple generations. The F1 offspring all expressed the dominant traits, while the F2 offspring showed Mendel's expected 3:1 ratio between dominant and recessive traits, supporting the hypothesis that the mutant traits were autosomal recessive. The experiment demonstrated how Mendelian genetics can be used to determine unknown genotypes through observing inheritance patterns over generations.

Mendel's Law of Independent Assortment states that allele pairs separate independently during gamete formation, meaning traits are transmitted independently of one another. Mendel demonstrated this through dihybrid crosses in pea plants, which resulted in a 9:3:3:1 ratio of traits in the offspring. His work established that inheritance follows simple probabilistic rules and discrete factors (genes) are passed from parents to offspring according to the laws of chance.

Biology 103 Laboratory Exercise – Genetic Problems
Introduction
Although the science of genetics has become a highly sophisticated discipline dealing
with the interactions of hereditary factors at the molecular level, it has its roots in the
basic laws of heredity initially discovered and presented by Gregor Mendel more than
one hundred years ago. Mendel's success in discovering these laws was due largely to his
application of the simple rules of mathematical probability - the laws of chance - to his
observations concerning the inheritance of certain characteristics in the garden pea plant.
Reginald Punnett and the Punnett Square
The Punnett square is a diagram used by biologists to determine genotypic probability
within the offspring from a particular genetic cross. The Punnett square shows every
possible genotypic combination of maternal alleles with the paternal alleles for a genetic
cross. Punnett squares only give probabilities for genotypes, not phenotypes. The square
diagram was designed by the British geneticist, Reginald Punnett (1865-1967) and first
presented to the science community in 1905. Punnett’s Mendelism (1905) is considered
the first popular science book to introduce genetics to the public.

The first step in solving a genetic problem is to establish the genetic symbols you will use
in your problem solution. Stay consistent by using these same symbols throughout the
problem solving process.
Represent dominant and recessive alleles (different forms of a gene) using traditional
genetic symbols. Dominant alleles should be represented with the capital version of an
alphabetic letter while using the lower case version to show recessiveness. For example:
B = black color, b = white color.
Each individual gene or trait is diploid (2n) in nature and therefore, must be represented
with two alleles. Continuing with the alleles mentioned previously, an individual may
have the genetic makeup BB, Bb, or bb when using those alleles.
Remember that gametes (sperm and egg) are haploid (n) and can only provide one allele
per trait. For example: B or b
An individual’s genotype contains the possible gametes that can be expected to be
produced by that individual. Much of genetics revolves around the probability of the
makeup of gametes. If the individual is homozygous, all of the gametes produced will
possess the same kind of allele. For example, an individual with the genotype BB would
be expected to produce only B gametes and individuals with genotype bb would produce
only b gametes.
If the individual is heterozygous, that is the individual’s genotype contains one dominant
allele and one recessive allele (Bb), the gametes produced will possess one or the other of
the two forms of the gene – B or b. ...

Gregor Mendel conducted experiments with pea plants between 1856-1863. Through his experiments, he discovered two fundamental laws of inheritance: the Law of Segregation and the Law of Independent Assortment. The Law of Segregation states that alleles segregate and are passed to gametes independently. The Law of Independent Assortment states that different genes assort independently during gamete formation. Mendel's work laid the foundation for modern genetics although it was not widely recognized until the early 20th century.
Drosophila Melanogaster Lab Report Essay
Drosophila melanogaster, or the fruit fly, is used to study genetics through laboratory experiments observing inheritance patterns across generations. The document describes experiments crossing fruit flies with different traits, such as eye color and wing shape. The results show that some traits, like white eyes and short wings, are inherited together, indicating genetic linkage. Other traits, like dumpy wings and brown eyes, also show linkage. The experiments support Mendel's laws of inheritance and provide insights into how traits are passed down from parents to offspring.

Mendel's laws of segregation and independent assortment govern inheritance. When crossing two heterozygotes with different alleles at the same locus, DaDb and DcDd, the alleles will segregate and assort independently. This results in offspring genotypes in a 1:2:1:2:1:2:1:1 ratio.

Mendel's laws of segregation and independent assortment govern inheritance. When crossing two heterozygotes with different alleles at the same locus, DaDb and DcDd, the alleles will segregate and assort independently. This results in offspring genotypes in a 1:2:1:2:1:2:1:1 ratio.

According to Mendelian genetics, a recessive trait will appear in an .pdf
- 1. According to Mendelian genetics, a recessive trait will appear in an offspring if and only if both parents contribute a recessive gene. If each parent has a dominant and a recessive gene, then the probability that their offspring will display the recessive trait is 1/4. The following questions assume a population of offspring bred from parents with one dominant and one recessive gene for each of the two traits considered. A certain strain of tomato is either tall (dominant trait) or dwarf (recessive trait). The same strain has either cut leaves (dominant trait) or potato leaves (recessive trait). Let E1 denote tall cut-leaf offspring, let E2 denote tall potato-leaf offspring, let L3 denote dwarf cut-leaf offspring, and let L4 denote dwarf potato-leaf offspring. Assuming that the traits are independent, compute the probability of each Ej. In 1931, J. W. MacArthur reported experimental results for n - 1611 offspring.'1 MacArthur observed o1 = 926, O2 = 288, O3 = 293, and O4 - 104. Use these data to test the correctness of the cell probabilities computed in part (a). Solution image of question is not clear please again uplaod it.................
