You have an opportunity in biology lab to observe the prepared, stained karyotypes of a stallion, a mare, and their foal offspring horses. banding patterns of some of the autosomes from the foal match those of the stallion, while others from the foal match those of the mare. this variability is produced in meiosis due to
(a)semi-conservative replication
(b) random fertilization
(c) non-random fertilization
(d) random alignment of chromosome pairs
(e) mutation

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

if you know your abc's you should be able to get your answer or just use google
