The A and B alleles are codominant, and the O allele is recessive. An AB blood type mother has children with a B blood type father (genotype BO). What are the chances that their offspring will have AB-type blood? Express in percentage.
A 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.)
The dominance pattern of a gene can be determined from the phenotypes of the parents and offspring. In the examples below,
assume that each parent is homozygous for the specific allele and that the progeny are heterozygous. Classify each example as
either complete dominance, incomplete dominance, or codominance.
Complete dominance
Incomplete dominance
Codominance
