1. In guinea pigs, rough and black are dominant. A rough-coated black guinea pig, whose mother was smooth and white, is mated with a smooth white animal. What kinds of
offspring (genotype and phenotype) should they produce and in what relative number?

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

the answer for this question would be d. glaciers

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
