2. Indicate on your pedigree chart the individuals who are carriers by shading half of each circle or square.

This equation is used to calculate the genotype frequency, so 1 = 100% of the population.

2. Can the student tell from the blood type if the student is heterozygous or homozygous? Explain. (5 points) Yes, knowing your blood type would

What observations can you make regarding the gene pool and gene frequency of the surviving individuals?

Over five trials the average allele frequency with this change in the migration rate is 0.366.

4. Clear wing, Black eye, and Hairless (c, b, and h) are linked, recessive traits carried on

1. Suppose two Dd birds mate. What percentages of DD, Dd, and dd offspring would you predict? Use the Punnett square at right to help determine your answer.

Once the Punnett square for Question 12 is complete, calculate the ratio of purple and yellow kernels (recall that if the dominant trait is present, it will be expressed).

Calculate the ratios of the genotypes and phenotypes of the offspring in the F1 generation.

Now you have determined some facts about the grounded allele and the trait that it causes. Given what you know, do you expect the mutant F1 flies to be homozygous or heterozygous for the allele that causes the grounded trait? According to your reasoning, if you mated two mutant F1 flies, what percentage of flies would you expect to be wild type versus mutant in the F2 progeny? Draw a Punnett square of this cross to justify your answer.

You are also provided with a heterozygous female, and a homozygous recessive male for a genetic cross. In this particular female, all the dominant alleles are on one chromosome, and the recessive counterparts are on the other homologous chromosome. Due to a chromosomal condition, in the female no recombination occurs between the M and N loci. Normal recombination occurs between the L and M loci. Diagram this cross, and show the genotypes and frequencies of all offspring expected from this cross.

Using the Hardy-Weinberg equation, calculate the predicted genotype frequencies for each population scenario below. Place your calculations and data in the space provided below. Once you have calculated the frequencies, answer the conclusion questions for each one. Please remember that all calculations must be shown for full credit.

Based on your results for the female offspring, predict whether color blindness is a dominant or recessive trait. Explain your reasoning.

Moreover, the migration of individuals from one genetically distinct population to another is also an important way for alleles to be added to or subtracted from a local population. Whenever an organism leaves one population and enters another, it subtracts its genetic information from the population it left and adds it to the population it joins. If it contains rare alleles, it may significantly affect the allele frequency of both populations. The extent of migration need not be great. However, as long as alleles are entering

Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population; which is usually it is expressed as a proportion or a percentage ("Allele frequency," 2014). In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool ("Allele frequency," 2014). The frequencies
