What are the three laws of inheritance proposed by Mendel?
The three laws of inheritance proposed by Mendel include:
- Law of Dominance
- Law of Segregation
- Law of Independent Assortment
Q2
Which is the universally accepted law of inheritance?
Law of segregation is the universally accepted law of inheritance. It is the only law without any exceptions. It states that each trait consists of two alleles which segregate during the formation of gametes and one allele from each parent combines during fertilization.
Q3
Why is the law of segregation known as the law of purity of gametes?
The law of segregation is known as the law of purity of gametes because a gamete carries only a recessive or a dominant allele but not both the alleles.
Q4
Why was the pea plant used in Mendel’s experiments?
Mendel picked pea plants in his experiments because the pea plant has different observable traits. It can be grown easily in large numbers and its reproduction can be manipulated. Also, pea has both male and female reproductive organs, so they can self-pollinate as well as cross-pollinate.
Q5
What was the main aim of Mendel’s experiments?
The main aim of Mendel’s experiments was:
- To determine whether the traits would always be recessive.
- Whether traits affect each other as they are inherited.
- Whether traits could be transformed by DNA.
