Q. A true breeding plant is :
(a) Near homozygous and produces offspring of its own kind.
(b) Always homozygous recessive in its genetic constitution.
(c) One that is able to breed on its own.
(d) Produced due to cross-pollination among the unrelated plants.
Solution :
Correct option : A A plant having either dominant or recessive allele of a gene is said to be pure breeding or homozygous for that gene or trait. Due to the presence of both same type of allele, pure-breeding plants produce progeny of their own kind. A cross pollination of two unrelated plants produces heterozygous plants having one dominant and one recessive allele for a gene. Pure breeding plants are obtained by self-pollination only. Therefore, the correct answer is option A.
