I don't know if I am doing my biology homework right and want some conformation, so please help!
An example of one of the questions is:
In humans, free earl lobes (E) is dominant over attached ear lobes (e), and brown eyes (B) is dominant over blue eyes (b). A man with free ear lobes and brown eyes marries a women with attached ear lobes and brown eyes. Of four children, one has free ear lobes and brown eyes, one has free earlobes and blue eyes, one has attached earlobes and brown eyes, and one has attached ear lobes and blue eyes. Determine the genotype of the parents.
For the genotype I thought it would be: EeBb for both mom and dad. Can anyone tell me if this is right? I am wanting to do well on this assignment.
There are also 3 bonus questions I haven't learned about but we are suppose to use the net, anyways bonus marks sound nice so here are the questions;
1) In Humans, hemphillia is a sex-linked condition and normal blood clotting (H) is dominant to the condition of hemophilia (h). A women with hemophilia marries a normal man. What are the probabilities of them having children with hemophilia and their sexes.
2). In humans being right-handed (R) is dominant over being left handed (r), and normal vision is dominant over color blindness (which is sex-linked). Two right handed parents with normal vision have a son who is left handed and color blind. Determine the genotypes of the son and both parents. What can you tell me about the phenotypes of the parents
3) A normal women whose father was a hemophiliac marries a normal man. Determine the genotypes of the women and the man. Determine the possible genotypes for their children. What percent of male and female children would be hemophiliacs? What percent normal? Would any be carries.
