I'm pretty sure the recessive allele is expressed in a heterozygous individual.

Just letting u know tho, I'm not completely sure

Hope it is right and helps u tho...lemme know :)

The right answer is Dominant allele.

A dominant allele qualifies the allele that wins over the associated allele. When the genetic action takes place in complete dominance, the dominant allele totally eclipses the recessive allele at the heterozygous stage, whereas it only partially eclipses it when the genetic action is manifested in an incomplete dominance mode.

The dominant alleles are those that appear in the phenotype of individuals.

enzymes that move certain phospholipids between leaflets have also which of the following properties?A. play a role establishing

laiz [17]

Answer:

A. play a role establishing and maintaining membrane lipid asymmetry

Explanation:

Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:

flipases-move lipids from the exterior to the interior side of the membrane, energy required
flopases-move lipids in reverse comparing to flipases, energy required
scramblases-no energy required, bidirectional

Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).

(WILL GIVE BRAINLIST) Rabbits are very popular domesticated animals, so popular that there are over 300 breeds of domesticated r

dem82 [27]

1) Breed A average weight = 9 pounds. Breed B average weight = 12.125 pounds. 2) Parentals' genotype, female size, number of deliveries, food, competition. 3) Genetic and non-genetic factors.

<h3>What is an average?</h3>

The average is the arithmetic media.

It can be calculated by adding the values of all the provided numbers, and then dividing the result by the total amount of numbers.

1) Average weights

Breed A: 10, 8, 7, 10, 9, 9, 10, 9

Average: (10 + 8 + 7 + 10 + 9 + 9 + 10 + 9) / 8 = 72 / 8 = 9 pounds.

Breed B: 10, 12, 14, 13, 10, 15, 11, 12

Average: (10 + 12 + 14 + 13 + 10 + 15 + 11 + 12) / 8 = 97 / 8 = 12.125 pounds.

2) Influencing factors:

Genetics: Individuals' size and weight can be inherited from their parents.

Female size: If the female is small, there are more probabilities of having small progeny than big ones, especially if the litter is numerous. This factor is known as uterine capacity.

The Number of deliveries: It is also significant the female's number of deliveries. Very young inexperienced mothers produce smaller litters and small-sized progeny than expert mothers.

Food: Individuals that are fed with a compete high-quality food will be bigger and will weigh more than those that are fed with poor-quality food.

Competition: If litters are numerous or there are many individuals, competition for resources might increase, leading the individuals to express lower weight.

<h3>How to track the growth rate?</h3>

To track the growth rate, we could consider genetic factors and non-genetic factors.

Genetic factors are related to the parentals' genotypes. The progeny inherit the alleles from their parents, and allele combinations determine the size and weight of individuals.

Non-genetic factors refer to the parental conditions before mating, and to external environmental factors.

To track the growth rate of the two rabbit breeds we could

Analyze the phenotypes and genotypes of the parents.

Evaluate the state of each parent before mating. At this point, we could consider age, size, sèxual maturity, experience, number of deliveries, receptiveness, if females are still breastfeeding or if they have recently wean, among other factors to analyze.

We could also consider the birth weight and the weaning weight, which are highly correlated, and give information about nourishing during gestation and lactation.
