Question

Blood type in humans is an example of trait that has multiple alleles. The alleles for type A blood and type B blood are codominant, and type O blood is recessive to both type A and type B. If a girl with type AB blood has a brother with type O blood and a sister with type B blood, which of the following genotypes could it be possible for their parents to have?

AO and BO

AB and OO

AB and BO

AO and AB

Answer 1

its AO and BO i am 65 percnt sure on this u should research

Answer 2

The possible genotype is AO and BO.

An organism's genetic makeup is called its genotype, and it reflects all the alleles, or kinds of the gene, which are carried through the organism. Consequently, a test move can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.

What are the 4 main blood groups?

A person's blood type depends on the genes he inherited from his parents. ABO is the most well-known system for grouping blood groups, although there are other methods. There are four main groups in the ABO group: A, B, O, and AB. There are eight other blood groups in these groups.

More than 179 people in India are known to have Bombay blood type. If the organ donor belongs to the Bombay blood group, the donor liver must be free of A, B, and H antigens. In theory, the Bombay blood group donor can donate a liver to any blood group (universal donor).

A genetic cross between respective genotypes is shown below.
