What is the relationship between the number of active genes and color of the skin

Biology
1 answer:
Leto [7]2 years ago
3 0

Skin color is polygenic trait meaning a lot of genes are significant in the expression of the trait. Such traits can have a multitude of variations showing continuous distribution because these non-epistatic genes have a cumulative effect on the skin color. The level of expression of these genes, majorly based on influence from the environment, will determine skin color. For example; the expression of the gene for melanin will be high in a person within the equator than in a person at the poles due to differences in sunlight exposure.

In insects what does hemi metabolism indicate
ArbitrLikvidat [17]

The hemi metabolism<span> indicates the three distinct stages of the life cycle of some insects: the egg, nymph, and the adult stage, or imago. It has no pupal stage just like the complete metamorphosis that undergoes pupal stage before turning into adult. Insects that undergo hemi metabolous metamorphosis go through gradual changes; develop from eggs into nymphs sometimes called larvae by some entomologists, that are similar in shape to the adults. You can distinguish the nymphs from the adults by looking for wings. Wing buds or wing pads may be present in late stage nymphs, but they are fixed in place against the body and are non-functional compared to the adults whose wings are fully developed. </span>

Komok [63]

Answer:

C) protein possesses a signal for localization within the Golgi apparatus.

Explanation:

Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.  

Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.
