Answer:

Brachialis

Explanation:

The Brachialis is an anterior skeletal arm muscle that extends from the medial arm to the superior area of the forearm. The brachialis fibers originate in the anterior part of the humerus and direct to the inferior part of the elbow, where they insert in the upper region of the ulna and distal radius. This muscle is an elbow flexor being used in every movement needed to approximate the anterior part of the forearm to the arm. It is a very thick and powerful muscle that acts with high speed.

Answer: There re two different types of phenotypes in the offsprings that is Round yellow and Round green.

Explanation-

As per the Mendelian inheritance, Round shape and yellow color of pea are dominant over wrinkled shape and green color of pea.

According to the question, genotypes of parents are- RrYy ( heterzygous for round and yellow) and RRYy ( homozygous for round and heterozygous for yellow).

The first parent can produce four different gametes that is RY, Ry, rY, ry whereas the second parent will produce only two types of gametes that is RY and Ry.

When they are crossed, they will produce two different phenotypes in the offsprings.
