Question

Describe the Mendel's law of segregation with the help of suitable diagram

Answer 1

Mendel's Law of Segregation:

This law is also known as Law of purity of gametes. Monohybrid cross forms the basis of this law. According to this law, in F2 hybrid, the dominant and recessive characters though remain together for a long time, but do not mix with each other and separate or segregate at the time of gametogenesis i.e., gamete formation.

Thus, the gamete formed receive either dominant or recessive character out of them.

For example, pure tall plant ( homozygous TT ) when crossed with the pure dwarf plant ( homozygous TT), hybrid tall plants ( heterozygous Tt ) are produced. This heterozygous hybrid has one factor of tallness and one factor of dwarfness in it.
