Autosomes are the chromosomes that do not carry the specific genes that determine the sex of an individual and they are homologous, whereas sex chromosomes carry the genes that determine an individual’s sex and they are not homologous because X chromosome is larger than Y chromosome.2 answ
Alleles A and B are always dominant over allele O. As a result, a person who has an AO genotype will have an A blood type, whereas an individual who has a blood type O has OO genotypes. Therefore, if an allele A is inherited from one parent and an allele B from the other parent, the blood type of the offspring will be AB.2 answ
