In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.
The answer is
c. he should write down data clear, step-by-step instructions as he goes along
Mendel wants to control the pollination of his pea plants because traits were not blended but they remain separate in the subsequent generations and also it is contrary to scientific opinion during his time
<u>Explanation:</u>
- Mainly, he wants to control because they were against the scientific opinion during his time.
- Mendel takes a pea plant for his experiment because it can be easily observable.
- Pea plant has seven traits and it can be pollinated by both the ways. One is self-pollination and the other is cross-pollination.
- Mendel did not know about the genes but he speculates the factors of formation in the traits.
- Mendel produces three laws, the law of dominance, the law of segregation, the law of independent assortment.
Maybe they came from different groups or mixed semen
