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.

 

AspectDescription
IntroductionA 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.
