Answer:

In a diploid organism there are two copies of most genes.

The versions of the genes are called alleles.

Explanation:

Hello!

The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).

When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.

Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.

In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.

The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.

Glucose is generally phagostimulatory (stimulates eating) for animals. The observation that cockroach populations exposed to poi
xxMikexx [17]

The correct answer is:

A. Will have a intermediate trait 3. Glucose aversion is a genetically-determined incompletely dominant trait

B. Will refuse glucose 2. Glucose aversion is a genetically-determined dominant trait

C. Have a mix of traits depending on experience 4. Glucose aversion is a learned behavior

D. Will accept glucose 1. Glucose aversion is a genetically-determined recessive trait

If we put it simple and say that for example glucose aversion is genetically determinated, with the genotype AA and eating glucose with the genotype aa. The offspring will have Aa genotype (heterozygous). Depending on which phenotype is expressed in heterozygous we can conclude whether the trait is dominant or recessive or due to earned behavior.

A graded hyperpolarization of a membrane can be induced by _____.
Doss [256]

Explanation:

In biology, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. That is, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in the membrane voltage in which the membrane potential is more clearly positive or negative, are hyperpolarizations.
