the paper doesn’t have to be 550 just follow instructions below for class
Two parents consult a genetic counselor. They do not understand why all their sons are colorblind (an X-linked trait) but none of their daughters are colorblind. Both of the parents appear normal. How would you explain this to the parents?
Your “answer post” should be at least 100 to 150 words and should reflect:
1Your thinking process (why you believe the way you do)
2Facts supporting your belief/thoughts
3supporting your facts
For each question you must explain your thought process on how you came to the result. Do not just state the answer!!
1. Tallness (T) in snapdragons is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heterozygous condition results in pink (Rr) flower color. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white flowers. What are the genotype and phenotype of the F1 individuals?
2. A man with type A blood marries a woman with type B blood. Their child has type O blood. What are the genotypes of these individuals? What other genotypes, and in what frequencies, would you expect in offspring from this marriage?
