Question

has a different combination of alleles compared to both of its biological parents?
choose 2 answers:
a half of the organism’s chromosomes are inherited from one parent, and the other half are inherited from the other parent.
b the cell that results from fusion of the parents’ gametes undergoes multiple mitotic cell divisions as the organism begins to develop.
c gamete formation in the parents can result in alleles that were once on different chromosomes being located on the same chromosome.

Explanation:

• For option A: In sexual reproduction, offspring inherit half their chromosomes from each parent. This mixing of chromosomes from two parents leads to a new combination of alleles different from either parent.
• For option C: During gamete formation (meiosis), processes like crossing - over can rearrange alleles. This means that alleles that were on different chromosomes in the parent can end up on the same chromosome in the gamete, and when combined with the other parent's gamete, it creates a new allele combination in the offspring.
• Option B is about mitotic divisions after fertilization, which is about growth and not about creating a new allele combination different from the parents.

Answer:

A. Half of the organism’s chromosomes are inherited from one parent, and the other half are inherited from the other parent.
C. Gamete formation in the parents can result in alleles that were once on different chromosomes being located on the same chromosome.
