what are the possible blood types of an offspring of a cross between an individuals that are type AB and type O blood?

A or B

Explanation:

AB is dominant 'o' is recessive

Drawing the punnet square :

A B __

_ o ___ Ao Bo

_ o ___ Ao Bo

Here, the 'o' allele is recessive, therefore the A B allele overshadows the 'o' allele,

Hence, the possible blood group types the offsprings could have is ;

A, A, B, B. Meaning that each offspring will have a 50 - 50 chance of being in the A or B blood group.

There will be no possibility of the offsprings belonging to the AB or o blood group.

The punnet square depicts the possible outcome.

Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.
