<h2>Answer and Explanation </h2>

A nonmetal (or non-metal) is a biochemical component that frequently requires metallic characteristics. Materially, nonmetals tend to have moderately low melting and boiling points, and densities, are essentially inelastic if solid.

When a nonmetal bonds with a nonmetal the result is a covalent bond. A covalent bond is a chemical bond which includes the sharing of electron pairs among atoms. Water (H2O) and carbon dioxide (CO2) are examples of covalent bonds. In H2O, one oxygen atom joins with two hydrogen atoms.  

However they are habitually poor conductors of heat and electricity chemically, they manage to have approximately powerful ionization energy, electron relationship, and electronegativity charges.

In fruit flies, eye color is a sex-linked trait. Red is dominant to white.
ozzi

Answer:

The correct answers are:

1 a. X^RX^r - red eye color female

b. X^RX^R - red eye color female

c. X^RY - red eye color male

d. X^rY - white eye color male

e. X^rX^r - white eye color female

(2nd part can also be answered by above)

Explanation:

It is given that the eye color is a sex-linked character where Red eye color is dominant over white eye color in fruit flies. Sex-linked characters are the character that is a similar inheritance pattern except in the case of the male as there is a Y chromosome that does not carry the gene for the eye color trait so the trait will depend on the allele present on a single  X chromosome in males.

On the basis of this, the sex and color of eyes will be:

a. X^RX^r - red eye color female - Dominant character will mask the recessive white color and two copies of X which means female.

b. X^RX^R - red eye color female - both copies are dominant so red-eye color will be expressed and two copies of the X chromosome that means female

c. X^RY - red eye color male - One X and one Y chromosome that means male and only dominant allele present so red eye color.

d. X^rY - white eye color male - Only allele that is present is recessive with one Y chromosome that means male with white eye color.

e. X^rX^r - white eye color female - two X chromosomes with recessive allele which means white eye color female.
