Here are 4 sentences using 1 vocabulary word from Evolution Part 2 in context in each sentence:
1. Directional selection occurs when a trait at one extreme of a range is favored, gradually shifting the population away from intermediate forms.
2. Stabilizing selection maintains genetic equilibrium in a population by favoring intermediate traits and eliminating extreme variants.
3. Geographic isolation prevents gene flow when physical barriers separate populations into isolated regions.
4. Endosymbiotic theory explains how cellular organelles like mitochondria and chloroplasts originated as once free-living prokaryotic cells that became permanent residents within eukaryotic cells.

How DNA Determines Traits A distant alien planet similar to earth has been discovered. The most
popular species on the planet are called "uoieriffins".A, which are some hybrid of birds, lions, and
unicorns. ScienFsts, have recently obtained DNA samples and have mapped out 10 genes so far.
Your job as science students is to analyze the DN sequences of the yrieriffio samples to determine
which features each sample codes for. Determine which traits each type of ynigriffin has by
decoding the DNA. There are a total of 10 genes, which could be two possible versions.Before you
can decode the ONA samples you must FiRST transcribe the DNA to its complimentary mRNA
strand. Using the mRNA codons, you can configure the amino acids to determine the traits. AUG
is a start codon, and it signals the beginning of each gene. UAA is a stop codon and signals the
end of a gene. Though these start and stop codes would typically be seen at the start and end of
each and every gene, to save time we can assume they have already been translated for us. Tip:
Transcribe the all the mRNA first, then go back and translate the amino acids, and lastly determine
traits. Ulla Unigrij DNA: I CAT AGG GAG I CAAGGG TGACTT TIT | AAT AAT GAC GGG I mRNA:

In-class introduction to basic Punnett square set-up and problem solving, Part 1
Problem-solving tips:
· A Punnett square allows you to predict the possible genetic outcome of children based on the genetic make-up of the parents.
· First, read the problem and figure out whether the trait of interest or genetic disorder is found on the dominant allele or the recessive allele because that will have an impact on how you interpret the results of the Punnett square.
· Select a letter to represent the trait or disorder and define the dominant and recessive alleles. For example: For eye color, B (dominant) = brown eyes and b (recessive) = blue eyes. For achondroplasia (dwarfism), A (dominant) = achondroplasia and a (recessive) = normal allele.
· If it is a sex-linked question, remember to include the sexual genotypes of the parents (XX for mom and XY for dad).
· Write down all possible genotypes & phenotypes and use this information to help you set up the Punnett square.
1. Practice question on a human trait. In reality, eye color is controlled by multiple genes and is a complex trait. For simplicity, we’ll assume that brown eyes are dominant to blue eyes. Answer the questions below.
a) Select a letter for this trait and define the dominant and recessive alleles.
B (dominant) =
b (recessive) =
b) Write down all possible genotypes and phenotypes for individuals in the population
Possible genotypes
(the 2 alleles an individual has)
Possible phenotypes (the physical appearance of a trait)
Homozygous dominant individuals
Homozygous recessive individuals
Heterozygous individuals
c) Set up the Punnett square and solve this problem. Kristy is heterozygous and Mark has blue eyes. What percentage of their offspring will have blue eyes?
Kristy's genotype
Mark's genotype
a) Select a letter for this genetic condition and define the dominant and recessive alleles.
F (dominant) =
f (recessive) =
b) Write down all possible genotypes and phenotypes for individuals in the population
Possible genotypes
(the 2 alleles an individual has)
Possible phenotypes (the physical appearance of a trait)
Homozygous dominant individuals
Homozygous recessive individuals
Heterozygous individuals
c) Set up the Punnett square and solve this problem. Kristy and Mark are carriers for cystic fibrosis. The term carrier is only used when a condition is on the recessive allele. Carriers are heterozygous individuals who are normal and show no symptoms of the disorder, but they have the ability to pass on the mutated recessive allele to their offspring. What percentage of their children will be normal? What percentage of their children will be carriers?
Kristy's genotype
Mark's genotype
2. Practice question on a genetic condition. Cystic fibrosis (CF) is an autosomal, recessive condition that results in mucus buildup in the lungs and digestive system organs. As a result, CF .
