Question

Select the incorrect statement.

• A. Inbreeding increases homozygosity.
• B. Inbreeding is essential to evolve pure lines in any animal.
• C. Inbreeding selects harmful recessive genes that reduce fertility and productivity.
• D. Inbreeding helps in the accumulation of superior genes and the elimination of undesirable genes.

Answer 1

The correct option is C

Inbreeding selects harmful recessive genes that reduce fertility and productivity.

The correct option is C.

Explanation of the correct option:

1. Inbreeding selects the superficial genes that increase fertility and productivity rather than the harmful recessive genes.
2. It also aids in the accumulation of superior genes while removing less desirable genes.
3. As a result, the selection at each stage boosts the productivity of the inbred population.
4. Close and persistent inbreeding reduces fertility and even productivity.

Explanation of the incorrect options:

Option A:

Closely related organisms have nearly identical genes. As a result, subsequent progenies share the same gene pool, increasing homozygosity.

Option B:

Inbreeding will produce progenies with nearly identical genes, resulting in pure lines with the same characteristics.

Option D:

Inbreeding improves the good characteristics and increases fertility by removing harmful and undesirable genes.

Final answer: The incorrect statement is inbreeding selects harmful recessive genes that reduce fertility and productivity.
