1.) a.) Suppose the dominant allele frequency is 0.15, what is the number of homozygous dominant individuals you would expect to find in a population of 100 individuals? b.) Suppose you are trying to determine the allele frequency of hair texture in a group of 50 individuals. You notice 15 individuals have curly hair (HH), 25 have wavy hair (Hh), and 10 have straight hair (hh). What is the allele frequency of the dominant allele, "H"?

Consider the following scenario: In a population of 1000 individuals, 490 are homozygous dominant, 420 are heterozygous, and 90 are homozygous recessive. Answer the following questions about this population. How many total alleles does this population have? How many dominant alleles does this population have? How many recessive alleles does this population have? Based on your numbers from part a, calculate the following frequencies, and give a written description of each (i.e. what does each number mean in “real world”...

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

Case B: In this population, the frequency of the dominant allele, B, is 0.5 and the frequency of the recessive allele, b, is 0.5. However, in this situation any individual who is born with the dominant trait has a 50 % chance of not surviving to reproductive age. Assuming that mating is still random, what will happen to the allele frequencies (p and q) after 5 generations? (le. Will one allele increase or decrease?) Prediction (1 mark): Reason (2 marks):...
