In pea plants, round seeds (R) are dominant to wrinkled seeds (), and yellow seed color () is dominant to green seed color (y). The gene for seed shape and the gene for seed color follow the law of independent assortment and are not sex-linked. In a cross between
two RrYy parents, predict the fraction of offspring with round, yellow seeds.

What is the difference between sex-linked traits and autosomal traits in humans? a. sex-linked traits can only be passed from fathers to sons, while autosomal traits can be passed on from both parents to offspring of any sex. b. sex-linked traits are passed on through the x and y chromosomes, while autosomal traits are passed on through the other 22 chromosomes. c. sex-linked traits only affect females, while autosomal traits affect both males and females. d. sex-linked traits refer to genes that are on the x and y chromosomes, while autosomal traits refer to genes on all 23 chromosomes.
