1. Which blood types are dominant?
marishachu [46]

Answer: 1). A and B are both dominant (because A and B are codominant to one another)

2). E. All of the above

Explanation:

1). From the image above, A and B are both dominant because they are equally expressed when they occur in a pair (when they occur as blood type AB), also they are dominant because each of them expressed itself when it occurs in a pair with a recessive allele (IAi and IBi).

2). The children of a father with A blood and a mother with B blood will have all the four blood types: A, B, AB, and O. If each parent has a recessive allele, that is if each parent is heterozygous for his/her blood type (IAi for the father and IBi for the mother), the cross between them will produce all the four possible blood types.

See the attached punnet square for more information.

frozen [14]

Answer:

Disruptive Selection.

Explanation:

Disruptive selection, also known as selection diversification, explains shifts in population genetics that prefer extreme values for a trait over intermediate values. In this case, trait variation increases, and the population is split into two different classes. So, in the given case where A "U-shaped" distribution for a trait, with high frequencies of individuals who exhibit extreme values for a trait (and few individuals with medium values), is most likely to be caused by Disruptive selection.
