16. A couple has two children; one with a widow's peak and one without. If both parents have a widow's peak what do you know to be true? 1. Both parents are heterozygous for the trait 2. Both parents are homozygous dominant for the trait 3. Both parents are homozygous recessive 4. One parent is homozygous dominant the other is homozygous recessive
1. Armin and Annie are going to have a baby. Annie has dimples in her cheeks (a dominant trait), while Armin does not. You know that Annie's father has dimples in both cheeks, while her mother does not. Her mother must have the recessive trait. Annie's father has the dominant trait. but vou don't know if he is a homozygote or heterozygote. But you still know what Annie's genotype must be because Annie must have a recessive allele since that is all she could have inherited from her mother. Since Annie has a dimple you know she inherited a dominant allele from her father. What are the chances Armin and Annie's baby will have dimples? Determine the Phenotype and Genotype and its probability.

1. In humans, widow’s peak (W) is dominant over having a straight hairline (w). If a homozygous man with a widow’s peak has a child with a woman with a straight hairline, what are the odds the child will have a widow’s peak? Show work. 2. Ellis-van Creveld syndrome is a recessive inherited condition that results in 6-fingered dwarfism. Two parents without this condition have with Ellis-van Creveld syndrome. What are the genotypes of the parents and offspring? What are the odds that the son will have a 6-fingered child if his partner is a woman who is heterozygous for the condition? Show work. 3. The gene for dangling earlobes is dominant over the gene for attached earlobes. A woman with attached earlobes has a child with a man with dangling earlobes whose mother had attached earlobes. What is the probability that this child will have attached lobes? Show work. 4. In humans, normal pigmentation is due to a dominant gene, while albinism is recessive. A normally pigmented man has a…
