mezya [45]

Options for the question are not given. They are as follows :

A.  Mate them and see what color the offspring are—that will be the dominant color

B.  Mate them and see what color the offspring are—the other will be the dominant color

C.  Mate them, and then mate their offspring to see what color the next generation is

D.  Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color

Answer:

A.  Mate them and see what color the offspring are—that will be the dominant color

Explanation:

Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.

When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.

Compare and contrast the contributions of Neel, Pauling, and Ingram to our understanding of the genetic and molecular basis of s
taurus [48]

He demonstrated that SCD and sickle cell trait were due to the presence of abnormal 8-globin polypeptides in red blood cells. He demonstrated that the electrophhoretic mobility of B-globin from patients with SCD was different from that of healthy individuals. He demonstrated that both parents of multiple patients with SCD had low levels of sickled red blood cells. He hypothesized that SCD was a recessive trait and that the parents of patients with SCD would be heterozygous carriers. He demonstrated that the difference between B-globin polypeptides in individuals who were healthy and those with SCD is an amino acid substitution. He performed a peptide fingerprint analysis on B-globin from individuals with 84 84 and 89 88, which identified the segment of B-globin that was changed by the BS mutation.

A crop is treated with a pesticide and 98% of the insects are killed. what will most likely happen to the remaining insects?
Marina CMI [18]

The 2% of the insects will begin to reproduce and grow their population exponentially and in time enable the population to recover. This is if the population is large enough to enable random mating. The 98% reduction in population drastically reduces competition for the remaining individuals hence giving them abundant resources for them to thrive.

Aquatic ecosystems are governed by factors such as amount of oxygen, amount of light, and water movement.
34kurt
False

<span>Marine ecosystems like lakes and oceans have aphotic zones. Aphotic zones refer to the zones in the water where there is little or no sunlight. It is found in bodies of water were depths only receive less than 1% of sunlight penetrations. Bioluminescence is essentially the only light found in this zone and most food comes from dead organisms that sink at the bottom of lakes or oceans. </span>
