Question

Explain why law of segregation is also called law of purity of gametes.

Answer 1

Principle of segregation (law of purity of gametes) ... At the time of the formation of gametes, these two factors obviously separate orsegregate, otherwise recessive type will not appear in F2. The gameteswhich are formed are always pure for aparticular character.

Answer 2

Dear Student,

◆ Law of segregation -

• Mendel's law of segregation states that when two different alleles for a trait are brought together in an individual they stay together but at the time of gamete formation the two alleles separate from one another so that each gamete has only one allele.

# Law of segregation is also called law of purity of gametes because -

• According to law of segregation, gametes has only one allele for a trait and hence are pure for that trait.
• Hence, it is also known as law of purity of gametes.

Thanks dear. Hope this helps you...
