Answer:
freckles with straight hair
no freckles with straight hair
Step-by-step explanation:
In this scenario, having freckles is dominant over not having freckles, and curly hair is dominant over straight hair. The first parent is homozygous for freckles, meaning that they have two copies of the gene for freckles, and they have straight hair. The second parent does not have freckles and has straight hair.
There are two possible genotypes for the first generation offspring[F1] with respect to freckles: they could inherit one copy of the gene for freckles from each parent (meaning they would be heterozygous for freckles and would have freckles), or they could inherit two copies of the gene for not having freckles [meaning they would be homozygous for not having freckles and would not have freckles].
There are also two possible genotypes for the offspring with respect to hair type: they could inherit one copy of the gene for straight hair and one copy of the gene for curly hair (meaning they would be heterozygous for straight hair), or they could inherit two copies of the gene for straight hair (meaning they would be homozygous for straight hair and would have straight hair).
Given these possible genotypes, there are four possible phenotypes for the F1 offspring: freckles with straight hair, freckles with curly hair, no freckles with straight hair, and no freckles with curly hair. However, since both parents have straight hair, it is not possible for the offspring to have curly hair, so the only possible phenotypes are freckles with straight hair and no freckles with straight hair.
