- The allele for albinism ( c ) is recessive to the allele for normal pigmentation ( C ). A normally pigmented woman whose father is an albino marries an albino man whose parents are normal. They have three children, two normal and one albino. Give the genotypes for EACH person listed.arrow_forwardState at least three reasons why a person’s phenotype can’t always be determined from the genotype.arrow_forwardA gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a husband and wife, who are both carriers of the sickle-cell anemia allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele being equally likely. Complete parts a) through c) below. a) Genes are always written with the dominant gene first. Therefore, there are two instances the offspring could have genotype Ss (one if the mother contributes the dominant allele and the father contributes the non-dominant allele; and one if the father contributes the dominant allele and the mother contributes the non-dominant allele). List the other two possible genotypes of the offspring. (Use a comma to separate answers as needed.)arrow_forward

What genotype(s) must the offspring have in order to have the phenotypic trait of hitchhiker’s thumb?
