Without Considering the Variation Provided by Crossing-Over,how Much Will Two

question 69

Multiple Choice

Without considering the variation provided by crossing-over,how much will two siblings from one set of parents vary from each other?

• A)All siblings from the same parents are identical to each other and demonstrate traits that are exactly halfway between their parents' traits.
• B)Siblings receive 100% of one parent's genes or the other parent's genes so they will either be identical if they receive the same parent's genes,or nothing alike if they receive different parent's genes.
• C)Siblings inherit essentially 50% of their genes from each parent,but two sibling offspring may share with each other from zero to 23 chromosomes in common from each parent and therefore vary widely from each other.
• D)Siblings inherit copies of the same 23 pair of chromosomes from each parent and only crossing-over provides any differences between siblings.
• E)There is one chance in 23 of getting identical sets of chromosomes from one parent,times two because there are two parents; therefore two siblings out of 46 will be identical except for the extent of crossing-over.
