Looking at the image of Amanda's chromosomes, is her hair texture rough or smooth?
rough
smooth
Look at the image of Amanda's chromosomes. The dotted chromosome came from her mom. The solid chromosome came from her dad. Does Amanda's mom have rough hair?
yes, because she has at least one dominant allele
no, because she doesn't have a dominant allele
it cannot be determined because we do not know mom's other allele for texture
Look at the image of Amanda's chromosomes. The dotted chromosome came from her mom. The solid chromosome came from her dad. Does Amanda's dad have rough hair?
yes, because he has at least one dominant allele
no, because he doesn't have a dominant allele
it cannot be determined because we do not know dad's other allele for texture
In a case of x-linked traits, what percentage of offspring will have colorblindness when a carrier mom and a colorblind dad are crossed?

Why is it not possible for males to be carriers of x-linked traits?
because they do not have an X chromosome
because they have two X chromosomes
because they only have one X chromosome
