Question 26
In guinea pigs, curly hair is dominant over straight hair. Two curly-haired parents have an offspring with straight hair. What does that tell you about the genes in the parents?
Both parents have only the curly genes
Both parents have a straight gene that is hiding behind a curly gene
Both parents only have the straight genes
One parent has the straight genes, and one parent has the curly genes
In roses, red flower color is dominant to white flower color. What color offspring can be predicted from the cross shown?
