how to determine the possible gametes for a genotyope? RrTt??
Please help and it would mean a lot if you knew how to find a childs blood type based off the parents.
it would mean so much to me if you could answer both.
The first part of the question has to do with the Principle of Segregation. When gametes are produced, members of a gene pair separate into different gametes. Therefore, you must separate the genes Rr and the genes Tt when producing the gametes. This individual is a dihybrid(heterozygous for two traits). Therefore, you must place one member of each gene pair into a gamete. The possible combinations of r's and t's are--RT, Rt, rT, rt. Those are the four possible gametes this individual can produce. For the second part of the question, blood type is inherited in the following manner. Allele A and B are co-dominant and allele 0 is recessive to both. Possible genetic combinations include AA and A0 which produce an individual with type A blood, BB and BO which produce an individual with type B blood, AB which produces an individual with type AB and 00 which is the only combination that produces an individual with the recessive type O.
