Question

multiple choice 1 point
in elks, brown fur color is dominant over black fur color.
if a homozygous brown fur elk (bb) bred with a black furred elk (bb), what are the changes that their child would have brown fur?
0%
25%
50%
75%
100%

Explanation:

Step1: Identify parent genotypes

Parent 1: $BB$ (homozygous brown), Parent 2: $bb$ (black)

Step2: Determine gamete types

Parent 1 gametes: all $B$; Parent 2 gametes: all $b$

Step3: Calculate offspring genotypes

All offspring get $B$ from Parent 1 and $b$ from Parent 2, so all are $Bb$

Step4: Determine phenotype probability

Since $B$ (brown) is dominant, all $Bb$ offspring have brown fur. Probability = 100%

Answer:

100%
