Question

Throughout the reflection, make sure you have a copy of the Student Guide and your data table.

In your experiment, you tested this hypothesis:

Hypothesis: If either parent mouse passes a dominant allele, then the offspring will have black fur.

You confirmed the above in steps 1 through 3, in which you changed the
of the
parents and predicted the fur color, or
, of the offspring.

Answer 1

You changed the genotypes of the parents and predicted the fur color, or phenotype, of the offspring.

(Genotype = the allele combination each parent carries; phenotype = the physical trait shown, here fur color.)
