Continous selfing in a plant increases
A. Homozygosity
B. Heterozygosity
C. Hemizygosity
D. Homogenecity
Answer: Option A
Solution(By Examveda Team)
Continuous selfing in a plant increases Homozygosity.Selfing increases homozygosity at a rate of 0.50 per generation. Increased homozygosity can uncover recessive deleterious variants and lead to inbreeding depression unless it is countered by the loss of these variants by genetic purging.
Increased homozygosity also weakens the mixing effects of recombination because it takes place between highly similar chromosomes.
