Eye pigment in a particular strain of fly is determined by two genes. An autosomal gene that controls the color of the pigments
Semenov [28]

RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.

Option D

<h3><u>Explanation:</u></h3>

The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.

As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.

As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.

So the most possible cross that is given here is RrXtXt×RrXTY.

Kipish [7]

Answer:

See

Explanation:

Given:

Brown allele (B) is dominant over the white allele (b).

It will be assumed that the alleles are not related to the X and Y chromosomes.

See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)

For both parents hetero-zygous,

P1:

Genotype: Bb (100%)

Phenotype: brown (100%)

F1:

Genotypes : BB, Bb, bB and bb in equal proportions, i.e.

BB (25%), Bb (50%), bb (25%)

Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)

Enzymes are used in moving sections of DNA that code for insulin from the pancreas cells of humans into a certain type of bacter
victus00 [196]

Answer:

Human insulin

Explanation:

The process where by region of a DNA that codes for a particular function is transferred between organisms into cells Is described as gene transfer. This process can be used to enhance the mechanism of producing a gene that is not originally present in such organisms before. Therefore if the gene that code for insulin is inserted into a bacterial vector , the offspring of such bacteria will be able to synthesize insulin in their cell
