Two Siamese and three Persian cats survive a shipwreck and are carried on
driftwood to a previously uninhabited tropical island. All five cats have normal ears,
but 3 carry the recessive allele for folded ears (genotype is F1).

Calculate the frequencies of alleles F and fin the cat population of this island.

what is the frequency of the homozygous (normal ears), heterozygous (for folded ears), and homozygous (folded ears) cats if these cat mate randomly and produce 100 offspring?

What is the allele frequency of the dominant and the recessive trait if the offspring in the second generation produces offspring with the following L frequencies: 50 homozygous, 30 heterozygous, and 20 homozygous folded ears?

Does the cat population is in Hardy-Weinberg equilibrium? Explain

In a population of 100 individuals, the number of homozygousrecessives is 4. Let’s assume that you can distinguish theheterozygotes from the homozygous dominants. There are 80heterozygotes, and 16 homozygous dominants.
b. What is the frequency of each allele?
c. What would you estimate the allele & genotype frequencies tobe if you only knew that there were 4 homozygous recessives out of100 individuals, and you knew nothing else about the population’sstructure?
Thanks!

Suppose that for a trait that is determined by a set of twoalleles, the observed frequency for homozygous dominant, homozygousrecessive, and heterozygous are 0.64, 0.26, and 0.1, respectivelyfor a certain population. Calculate the frequency of p, thedominant allele, and then perform a chi-squared test with analpha-value of 0.05 to test if the population is in Hardy-Weinbergequilibrium with a random sample of 1000 individuals.

1. In a certain population of African people, 9% of the population is born with sickle cell anemia. This is a recessive disease. What % of the population is:

Homozygous Dominant?

Heterozygous?

2. The frequency of the allele "z" in a population is 65%. Find the % of the following:

Homozygous recessive?

Heterozygous?
