Title: #35 $ - Genetics- Polygenic Traits Post by: Aliya1 on Apr 25, 2018 Hi, i added questions #35 and #36 by accident in my last post :yelling:
Here's #35. Use the following information to answer the next two questions. Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced. The probability of obtaining a female or male parakeet is the same as for humans. What is the probability of obtaining a male green parakeet when a green parakeet heterozygous for both genes is crossed with a white parakeet? Select one: a. 0.75 b. 0.13 c. 0.25 d. 0.50 I think the answer is c #36. A green parakeet crossed with a white parakeet produced offspring with four different colour patterns. What is the genotype of the green parakeet? Answer suggestions: BBYY,BBYy,BByy,BbYY,BbYy bbYY,Bbyy,bbYy, bbyy. So which one of these asnwers is the genotype of a green parakeet?
