Question

list 3 laws of inheritance of traits by G.J MENDAL . and why he was not famous scientist

Answer 1

1. Law of unit character and dominance .
2. Law of segregation.
3. Law of independent assortment.

Answer 2

Mendel proposed three laws:

Law of Dominance

The Law of Segregation

Law of independent assortment


Exception of law of dominance:

Incomplete dominance

In incomplete dominance when a red snapdragon flowered plant is crossed with a white flowered plant an intermediate phenotype appears in the F1 hybrid instead of a parental phenotype.

Exception of law of segregation:

Nondysjunction

During meiosis homologous chromosomes/sister chromatids and hence genes may move to a common gamete violating law of segregation.


Exception of law of independent assortment:

Linkage

When genes are present on the same chromosome they tend to remain together and enter into the same gamete. This is the reason behind deviation of dihybrid test cross ratio from 1:1:1:1 and occurrence of parental combination in high frequencies.

I think there are so many exception in his laws so he was not become a famous scientist.
