- hw #5 Genetics problemProblem 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 homozygous dominants (BB) were 64% of the population . a) What would be the percentage of pink heterozygotes and white homozygotes?Are these all correct? Last two questions are 8. What is the critical value? Round to two decimal places. 9. What is your conclusion from the chi-square test? option 1: Fail to reject H option 2: Reject Ho
