Question

compare the predicted values to the simulated values
black fur and black eyes\tblack fur and red eyes\twhite fur and black eyes\twhite fur and red eyes
predicted fraction\t16/16\t0/16\t0/16\t0/16
predicted percentage\t100%\t0%\t0%\t0%
simulated fraction\t10\t0\t0\t0
simulated percentage\t100%\t0%\t0%\t0%
the data confirm that black fur and black eyes are \tbecause even though one of the parents was homozygous for both white fur and red eyes, \toffspring had black fur and black eyes.
done

Explanation:

1. For the first blank: In genetics, when a trait appears in all (or nearly all, here predicted 100% and simulated 100%/10 out of 10) offspring even with a homozygous recessive parent for other traits, the trait is dominant. Black fur and black eyes show 100% occurrence, so they are dominant traits.
2. For the second blank: The simulated fraction for black fur and black eyes is 10 (and predicted is 16/16, but the simulated count is 10, meaning all (or 10) offspring had black fur and black eyes, matching the dominant trait expression.

Answer:

First blank: dominant traits; Second blank: all (or 10, based on the simulated fraction)
