Alice has type A blood and her husband mark has type B blood. Their first child, Amanda, has type O blood. Their second child has type AB blood. What is Alices genotype? Whats Marks genotype? Explain why.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

looks like the answer is     c     to me!

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
