Question

In breeding a new genetic variety of a crop by hybridisation, superior recombinants are self pollinated for several generations till they reach a state of

• A. Uniformity
• B. Heterozygosity
• C. Homozygosity
• D. Both (1) and (3)

Answer 1

The correct option is D Both (1) and (3)

After the hybridization of two selected parent plant species, the recombinants with the desired combination of characters are selected. These hybrids are then self-pollinated for several generations so that they reach a state of uniformity or homozygosity so that the desired characters will not segregate in the progeny.

(Uniformity and Homozygosity are synonymous for the state of possessing two similar alleles for the same genes, one acquired from each parent.)

So, the correct answer is 'Uniformity' and 'Homozygosity'.
