Question

Law of independent assortment is ___.

• A. Applicable to all genes on all chromosomes
• B. Applicable to all dominant genes only
• C. Applicable to those genes present on the same chromosome
• D. Not applicable to genes present on the same chromosome

Answer 1

The correct option is D

Not applicable to genes present on the same chromosome

According to the law of independent assortment ‘when two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters’. However if the two characters considered are from two different genes, present on the same chromosome then they do not separate from each other and get passed on together, unlike the genes that are on different chromosomes that segregate independently. Therefore, the law is applicable only to genes present on different chromosomes.
