Problem 2) Skin colour in dolphins is determined by a single gene showing incomplete dominance giving rise to 3 phenotypes Brown, Pink & White. A survey of a large population of dolphins was carried out and the phenotypes recorded. However a student who had some of the data stored on their phone fell overboard and unfortunately the data was lost. The only data saved was that the brown homozygotes (BB) were 59% of the population . a) What would be the percentage of pink heterozygotes and white homozygotes? b) What percentage of the gametes that give rise to the next generation of dolphins in this population will contain the white W allele?

PROBLEM 1. In a certain plant, yellow fruit, Y, is dominant to white fruit, y. A heterozygous plant with yellow fruit is crossed with a plant with white fruit. Determine the probable genotypic and phenotypic ratios resulting from this cross. Determine the probable genotypic and phenotypic ratios expected from crossing two heterozygous plants of Problem 1.

EXERCISE 6 HARDY-WEINBERG EQUILIBRIUM Work in a small group or alone to complete this exercise. In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and f'is the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (F) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (f ) and 70% (0.7) are dominant (F). 1. Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation. Be sure to show your work. 2. You have collected data on the observed genotype frequencies of the next generation. They are 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not?

12-Human Mendelian Traits & Hardy-Weinberg Equilibrium Use the Hardy-Weinberg equations to estimate the number of people in the class with each genotype. 2²2² = ¾/3 = 1 =1/12 a. Start by finding q², the frequency of the homozygous recessive genotype (tt). 5 9=√13=0.577 # of non-tasters total number of people 15 P+9 = 1 -> p = 1-9 = 0.423 2pq=0.488 pa= 0.179 b. Take the square root of q' to find q, the frequency of the recessive allele in the population (1). 9² C. Since p + q = 1, you can solve for p, the frequency of the dominant allele in the population (7). e. d. Now use the other form of the equation to find the other genotype frequencies: p² + 2pq+q² = 1 TT frequency=p²=_ Tt frequency = 2pq= tt frequency = q² = (you already have this As a check on your work, these three values should add up to 1. Calculate how many in the population have each genotype by multiplying each frequency by the total number in the population. 3 # of TT people = p² x total number of people: # of Tt people…
