Law of independent assortment says that assortment of one gene pair is independent of assortment of other gene pair which means each contrasting gene pair bears no association with other pairs of contrasting character and behave and segregate independently.

This allows the combination of new characters in the offspring. So it helps in increasing the genetic variability in the gene pool. Therefore law of independent assortment tells that inheritance of one trait had no effect on the inheritance of another.

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin

worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it
