Question Solved1 Answer Ксения Александровна Фед... Today at 11:54 Your task for today: 1) to solve two problems on genetics. 1. Curly hair of humans is a dominant trait, and smooth hair is a recessive trait. The second gene is for blood groups, both genes are independent. Parents both with curly hair have two children: one - smooth hair and I blood group, the second one - curly hair and IV blood group. What is the probability of birth of a child with curly hair and Il blood group? 2. In the family where the wife has I blood group and husband - IV blood group, and both have normal vision, the son was born with III blood group and color blindness. Find out the probability of the birth of a son healthy and his probable blood groups. Color blindness is a trait linked with X- chromosome, recessive. 2) Problem on protein synthesis: 8. Strand of DNA: 3-TAC AAC GAC ACA TAT- 5'. Draw a scheme of translation. What changes will occur in case of loss of the twelfth nucleotide on the left?
