Q

What is an example of the law of segregation

A

Pair of chromosomes go through meiosis each sex cell gets 1 allele (Aa ——-> A for 1 and a for another), one trait punnet square

Q

The separation and distribution of genes to gametes is a random and independent process; genes for different traits separate independently of one another and are randomly assorted; the segregation of any pair of chromosomes does not affect the probability of segregation of other pairs

A

Law of independent assortment
