SpyIntel [72]1 year ago

Gene frequencies are the frequencies and occurrences of the alleles in the population. Small populations allow the gene frequencies to change by the chance. Thus, option A is correct.

<h3>What is gene frequency?</h3>

The gene frequency is also called the allele frequency which shows the expression of the particle allele and trait in a population. It occurs in the smaller population by chance.

The smaller population has a low number of individuals as compared to a larger population. They show a greater number of genetic drift that show evolutionary changes at a faster rate.

Therefore, option A. smaller populations show gene frequencies.

During the _______ phase, the muscle is returning to resting length.
tangare [24]

Answer:

The correct answer is: Eccentric phase.

When talking about movement, we are talking about the activation of muscle fibers in order for this process to happen. In order for this to happen, motor neurons must activate the phases of muscle excitation, contraction and relaxation, so that the sarcomeres, and thus the fibers, can generate movement.

In essence, there are three stages, or phases, to complete muscle movement:   the concentric phase, which is when the muscle fibers are excited and begin the process of contraction. This means the muscle fibers will contract and generate movement, generating a shortening. Then we have the isometric stage, a moment in which there is no longer any more shortening of the muscle fibers, so basically, the movement is held and there is no further contraction, but neither is there relaxation of the muscle fibers. Finally, we have the eccentric phase. This phase is characterized precisely because it is the moment when the muscles begin to return to their resting position.

Can someone pls help me ​
frozen [14]

Answer:

Explanation:

a. Since both the parents are carriers, they have one allele that is the gene for the normal trait and one gene that is for the sickle cell trait. So the genotypes of the parents are Hh

b.   If we use a punnett square:

                    H            h

         H       HH           Hh

         h        Hh           hh

Genotypic ratio: 1 HH: 2Hh: 1hh

Phenotypic ratio:      1 normal blood cell: 2 sickle cell carriers: 1 sickle cell disease
