I don't usually do this but these are really beyond me.Color species in a species of duck is determined by 1 gene wit 3 alleles: H and I are codominant and i is recessive to both. How many phenotypes are possible?If a couple both are hetero. for a recessive train what is the probability of: all 3 kids having normal phenotype, 1 or more kids showing trait, all 3 showing trait, at least 1 being phenotypically normal?The genotype of F1 individuals is AaBbCcDd. What is the probability that F2 will have the following: aabbccdd, AaBbCcDd, AABBCCDD, AaBBccDd, AaBBCCdd?What is probability that each of these offspring will be produced? AABBCC x aabbcc => AaBbCc; AABbCc x AaBbCc => AAbbCC; aaBbCC x AABbcc => AaBbCc.Karen and Steve each have a sibling with sickle-cell disease. Neither of them or their parent have the disease, and none have been tested to reveal sickle-cell trait. Based on this, calculate the probability that if the couple had a child, it would have sickle-cell disease.
