Answer:
<em>The correct option is D) The expression of certain genes is affected by temperature.</em>
Explanation:
There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes.
Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.
In the winter, the enzymes controlling the fur might become degraded. A s a result, the genes are not able to express themselves. Hence, a white coat occurs.
Answer:
Mother, meiosis II
Explanation:
Red-green color blindness is a human X-linked recessive disorder. A young man with a 47,XXY karyotype (klinefelter syndrome) is color blind. His 46,XY brother also is color blind. Both parents have normal color vision.The nondisjunction occured in mother during meiosis II that gave rise to the young man with Klinefelter syndrome.
Etiology:
Meiotic Non-disjunction of the chromosome pairs during the First or second division of gametogenesis. Because of the extra chromosome, individuals with the condition are usually referred to as 47XXY. As in the above mentioned scenario, meiotic nondisjunction during meiosis II in the mother resulting in the failure of the sister chromatids to separate during meiosis II thus resulting in too many chromosomes.

“Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.”
“As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow.”
