Answer:
A single gene on the Y chromosome plays a crucial role in the parental development of the testes.
Explanation:
Y chromosome is present only in males and this chromosomes is the distinguishing factor which separates males from females. It is the smallest chromosome but of utmost importance due to its sex determining feature. Up till now, studies show that Y chromosomes only carry limited amount of genes.
The Y chromosome, most importantly, comprises of the SRY gene. This is the gene responsible for determining the testis and for the development of the testis. The SRY gene is responsible for sex determination.
When we use water, we often use too much. We waste it. When washing cars, showering, brushing our teeth etc. Because of wastefulness, there are places that don't have the luxury of being able to wash their car well, and can't water their lawns for more than a few minutes a day.
I hope I was able to help. Best of luck.
1. shotgun
2. inbreeding
3. cloning
4. Y chromosomes
5. The Human Genome Project sought to map a human's entire genome.
6. Inbreeding is a type of selective breeding that occurs when individuals with similar characteristics continue to be bred in an attempt to keep a certain set of traits. However, inbred organisms are genetically similar, and the probability that members of the population will receive mutated alleles leading to disorders is high.
7. Since no two humans have the same DNA, except for identical twins, forensics can take advantage of this fact by using DNA fingerprinting to solve crimes, convict wrongdoers, or overturn unjust convictions.

Chloroplasts are organelles found in plant cells that conduct photosynthesis. Chloroplasts absorb light and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
