Question

what is law of inheritance?

Answer 1

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Answer 2

There are three laws of inheritance:-
1.Law of Dominance and recessiveness:- when allele governing a trait masks the expression of other allele,such allele is called the dominant allele and other allele is called recessive allele. To express a recessive trait the alleles must be homozygous.
2.Law of segregation:- During gamete formation the pair of genes at homologous Chromosomes segregate and only one Gene comes in a gamete.
3.Law of independent assortment:- in case of dihybrid cross the male gamete carrying two types of alleles of two traits are independent to meet with any type of female gamete to form the zygote of next generation. Hope it helps.
