Answer:

Natural protein fibers.

Explanation:

Fibers such as wool, hair,and silk, are made of protein. These are all natural fibers.

The pl promoter is derived from

alexandr402 [8]

You have to have both the pL promoter as well as a second system of the cI repressor which controls the pL promoter.
When the cI repressor is expressed it will bind onto the operator region of the pL promoter and prevent expression.
When the cI repressor is not expressed it can't bind to its operator and the pL promoter (which is very strong) can express whatever gene it is upstream of.
So you need to have both for transcriptional control. you don't need the rest of the phage!

In some breeds of mice, yellow coat color is

Elis [28]

In the exposed lethal genes cause the individual's death during embryionic development before being born. H0m0zyg0us dominant individuals do <u>not get born</u>. Yellow: 2/3. Grey: 1/3. Phenotypic ratio: 2:1

<h3>What is complete dominance?</h3>

When the dominant allele completely masks the expression recessive allele, we talk about complete dominance.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait.

The dominant allele is hiding the expression of the recessive allele.

<h3>What are the lethal genes?</h3>

Refer to genes that impede the normal development of the individual.

They can cause death during embryo development <u>before the individual gets born, </u>

They can cause the individual's death after being born and <u>before reaching </u><u>sèxual maturity</u><u>. </u>

Let us assume that mice color is coded by a single diallelic gene that expresses complete dominance.

<u>Available data</u>:

Yellow color is dominant over grey color.

Yellow is coded by the dominant allele Y
Grey is coded by the recessive allele y

Genotype YY → Yellow and lethal

Genotype Yy → Yellow

Genotype yy → Grey

The cross would be as follows,

Cross: Yy x Yy

Gametes) Y y Y y

Punnett square) Y y

Y YY Yy

y Yy yy

F1) Considering ONLY the successfully born individuals

<u></u>

<u>Genotype</u>

2/3 = 50% of the progeny is expected to be heter0zyg0us, Yy.

1/3 = 25% of the progeny is expected to be h0m0zyg0us recessive, yy.

<u></u>

<u>Phenotype </u>

2/3 = 50% of the progeny is expected to be yellow, Yy.

1/3 = 25% of the progeny is expected to be grey, yy.

The phenotypic ratio is 2:1
