Which one of the following is not an advantage of inbreeding?
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. |
