Question

A true breeding plant is
  1. Near homozygous and produces offspring of its own kind.
  2. Always homozygous recessive in its genetic constutition.
  3. Produced due to cross-pollination among the unrelated plants.
  4. One that is able to breed on its own.

A
Always homozygous recessive in its genetic constutition.
B
Near homozygous and produces offspring of its own kind.
C
One that is able to breed on its own.
D
Produced due to cross-pollination among the unrelated plants.

Verified by Toppr

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.
