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.
Answer:
The respiratory centers that control your rate of breathing are in the brainstem or medulla. The nerve cells that live within these centers automatically send signals to the diaphragm and intercostal muscles to contract and relax at regular intervals.

<span>Electrophoresis separates polypeptide chains and DNA chains
by their fragment sizes after they have been cut by restriction enzymes are
specific sites. Genetic testing involves checking genetic
disorders by evaluating DNA sequences or protein amino acid sequences. By using
restriction enzymes to cut DNA or polypeptides at specific sites, then run them
on an electrophoresis, bands will form that will help indicate whether one has an
abnormal sequence at the target site. If so, further analysis is used to
determine the sequence by use of next-generation sequencing machines</span>
