Blood typing in humans depends on three alleles. 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 children will have AB type blood?

25%

Explanation:

If a mother of blood type AB has children with father of blood type BO than there is a 25% chance that they had a child with blood type AB.

As the mother has two alleles A and B.

Father has two alleles B and O. So there are total of 4 sequences AB, AO, B, and BO.

AB 25%

AO 25%

B 25%

BO 25%

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.

answer; the correct answer is (beta)
