If two parents areheterozygous for such trait, the probability of having a normally pigmented child is 3//4 and having an albino child is ¼. What is the probability that 2 will be normal and 1 will be albino?Given the karyogram below, anSW Is this a male or female? female Do you see any abnormality?

List the gene or genes involved, list and define all allele symbols, and indicate the genotypes of the individuals you are crossing above the Punnett square. Answer questions that ask for a ratio as a ratio and questions that ask for a percent as a percent. In humans, albinism is a recessively determined trait. One form of hereditary deafness is also a recessive trait. Show the cross of a man who is heterozygous for skin pigmentation and heterozygous for hereditary deafness with a woman who is albino and deaf. Show the expected phenotype ratio of the offspring.Please answer fast 1.
