The allele for curly hair is dominant over the allele for straight hair. If you mated a curly-haired dachshund and a straight-haired dachshund, would you be able to accurately predict the probability of the offspring having curly hair? Why?(1 point)

Yes, because you know the genotypes of both dogs.

To accurately predict the probability of the offspring having curly hair, you need to know the genotype of both the curly-haired and straight-haired dachshunds. In this case, the allele for curly hair is dominant over the allele for straight hair. Let's assume that the genotype for curly hair is represented by "C" and the genotype for straight hair is represented by "c".
If the curly-haired dachshund is homozygous for curly hair, meaning it has two copies of the "C" allele (CC genotype), then all of its offspring will inherit at least one "C" allele, and therefore, have curly hair.
On the other hand, if the curly-haired dachshund is heterozygous for curly hair, meaning it has one copy of the "C" allele and one copy of the "c" allele (Cc genotype), then 50% of its offspring will inherit the "C" allele and have curly hair, while the other 50% will inherit the "c" allele and have straight hair.
Knowing the genotype of the straight-haired dachshund is not necessary in this case because the straight hair allele is recessive, meaning it will only be expressed if the individual has two copies of the "c" allele (cc genotype). Thus, regardless of the straight-haired dachshund's genotype, all of its offspring will have at least one copy of the dominant "C" allele and have curly hair.
Therefore, by knowing the genotype of the curly-haired dachshund, you can accurately predict the probability of the offspring having curly hair.
