According to the principle of segregation, gene pairs for a trait are split during the formation of gametes.
<u>Explanation</u>:
- This segregation was first observed by Gregor Mendel. He used pea plants for studying genetics.
- He crossed the pea plants and he discovered that traits in the offspring are not like the parental plants.
- He understands that alleles encoding the traits of each parental plant are separated during the formation of reproductive cells.
- By this only Mendel observed the principle of segregation. During meiosis only segregation of gene takes place and that produces reproductive cells called gametes.
Answer: Yes because the more the human population expands the more global warming and pollution there is. Right now in places like China you can see the sky because everyone is staying inside and not using their cars, if there were less people this wouldn't be a problem.
Explanation:
The respiratory system brings oxygen unto the lungs, while the circulatory system delivers oxygen throughout the body.
