Question

Mendel's first law of segregation definition

Answer 1

Mendel's law of Segregation (also called the law of purity of gametes). The two members of a pair of factors separate during the formation of gametes .they don't blend but segregate or separate into different gametes. The gametes combine together by random fusion at time of zygote formation.

Answer 2

Law of segregation

Law of segregation states that " During the formation of gametes . the alleles for each gene segregate from each other or separate from each other such that each gamete gets only one allele ."

Concept :

Suppose imagine this cross :

Dominant Brown eye BB is crossing with recessive blue eye bb

Note here that :

The formation of gametes will occur by taking only one allele from BB and another allele from bb

Their probability is 1/2

Here the alleles will be B and b particularly because there is no other choice.

From BB only one allele will be B itself and from bb the allele will also be b itself.
