In the early development of the human embryo, the epiblast which is the outer layer found in the embryo, it will eventually form the different germ layers which are called the ectoderm, the outer layer, the mesoderm that is in the middle layer and last, the endoderm which is found in the inner layer.

<span>During the early development of a human embryo, the epiblast eventually forms the ectodermal, mesodermal, and endodermal tissues.
Epiblast is a part of the inner mass cell whose primary function is to create these three types of tissues for the human embryo. Ectoderm is the most exterior layer of germ, mesoderm is the middle layer, and endoderm is the most proximal layer.

Why are populations, rather than individuals, the units of evolution?
dimulka [17.4K]

Explanation:

The unit of evolution is the population. A population consists of organisms of the same species that live in the same area. In terms of evolution, the population is assumed to be a relatively closed group. This means that most mating takes place within the population.

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers
fredd [130]

Answer:

we will know that the allelic frequencies are for R 0.95 and r 0.05

Explanation:

We know that the population is in Hardy-Winberg equilibrium, we deduce the following formula:

p + q = 1

p2 + 2pq + q2 = 1

data

R: red flower allele

r: allele blor blanca

p would be equal to the allelic frequency R

q will be equal to the frequency allelic r

2p = RR

2q = rr

2pq = Rr

If there are 25 white flowers in 1000 plants, their frequency will be:

2pq frequency of the Rr genotype

white flower = 25/10000 = 0.0025 = rr = 2q = 0.0025

we deduce that q is equal to 0.05

we replace the data with the previous formula

p + q = 1

p = 1-0.05

we get as a result

  p = 0.95

if p = 0.95 and q = 0.05

we will know that the allelic frequencies are for R 0.95 and r 0.05

In poultry, black is dominant to white, but the heterozygote is blue. If you consistently
balu736 [363]

Answer:

indeterminate

Explanation:

The answer would be <u>an indeterminate number of generations.</u>

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

<em>Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.</em>
