Question: Which one of the following is not an advantage of inbreeding?
A It exposes harmful recessive genes that are eliminated by selection.
B Elimination of less desirable genes and accumulation of superior genes takes place due to it.
C It decreases the productivity of inbred population, after continuous inbreeding.
D It decreases homozygosity.
Answer: It decreases the productivity of inbred population, after continuous inbreeding.
| Aspect |
Description |
| Introduction |
A reproductive strategy in which closely related individuals mate, leading to an increase in the frequency of homozygous alleles in their offspring. |
| Types of inbreeding |
· Full-Sibling Inbreeding
· Half-Sibling Inbreeding
· Cousin Inbreeding
· Linebreeding
· Self-Fertilization (in plants)
· Pedigree Inbreeding
· Royal or Dynastic Inbreeding
· Founder Effect Inbreeding |
| Advantages |
· Homozygosity for desirable traits in breeding programs.
· Preservation of specific genetic characteristics or breed standards.
· Rapid fixation of traits in small populations.
· Exposes harmful recessive genes that are eliminated by selection.
· Elimination of less desirable genes and accumulation of superior genes takes place due to it. |
| Disadvantages
|
· Increased risk of genetic disorders and health issues due to the expression of deleterious recessive alleles.
· Reduced genetic diversity, limiting adaptability to changing environments.
· Loss of heterozygosity for beneficial traits.
· It decreases homozygosity. |
