Answer

B
She inherited a chromosome that carries an allele for hair color from only her father.
C
She inherited a chromosome that carries an allele for hair color from only her mother.
D
She inherited a chromosome that carries an allele for hair color from each parent.

Explanation

Danielle inherited chromosomes from both her mother and her father, and those chromosomes carry genes with alleles that influence hair color. Her blonde hair can result from the combination of alleles she inherited from both parents, even though her father has brown hair. So the correct choice is “She inherited a chromosome that carries an allele for hair color from each parent.”
