If a corn plant was heterozygous for kernel color and seed shape, what would be the phenotype of the plant?

Ants and aphids often live near each other. The ants feed on the wastes produced by the aphids, and the aphids are protected fro

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

What would happen to the size of the carnivore population if the herbivore population increased?

The United States’ fossil fuel shortage of makes the country dependent on outside sources.

Rainbow [258]

The answer is oil.

The United States' fossil shortage of oil makes the country dependent on outside sources. Mineral oil such as crude oil or commonly known as petroleum came from the ancient fossilized organic materials. This resource is limited. The US is now facing a shortage in oil and becoming dependent to some countries such as middle-east countries.

A polypeptide in a wild type microbe contains the sequence Leu-Pro-Tyr-Ser-Pro. A phenotypic variant of the species has the pept

Katen [24]

Answer:

The mentioned case is an illustration of the missense mutation. A missense mutation is a kind of nonsynonymous substitution, that is, it is a mutation in which a variation in a solitary nucleotide leads to the formation of a codon, which encrypts for a distinct kind of amino acid.

When a missense mutation takes place within a DNA, a modification in one of the RNA codon sequences results at the time of transcription. This change in codon will ultimately result in the formation of a different amino acid, which gets presented within a protein at the time of translation. Like in the given case, a change in codon resulted in the substitution of the amino acid tyrosine with an amino acid cysteine.
