In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f).  A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non‑freckled, normal visioned girl or a non-freckled, normal visioned boy?   What is the probability that the first four children born to the couple will be freckled and normal visioned girls?

Finger mid-digital hair (M) is dominant over the recessive trait of no mid-digital hair (m). Freckles (F) is dominant over the recessive trait of no freckles (f). (It is important to note that this example of mid-digital hair and freckles cannot be explained with simple genetics, but for the purpose of this question, assume that it can.)A woman that is heterozygous for freckles and has no mid-digital hair is married to a man with no freckles that is heterozygous for mid-digital hair. The couple is expecting a child. Draw a Punnett square of this cross.

The questions below all refer to the following pedigree. The locus for allele D/d determines how cilia function within the body. Mutations at this allele cause abnormal ciliary function, resulting in a clinical disorder characterized by frequent respiratory infections (including in the ears, sinuses, and lungs), as well as infertility. In the pedigree, black circles/squares represent individuals affected by the disorder. White circles/squares represent unaffected individuals. Remember, if a trait is rare in a population (such as this one), we assume individuals marrying into the family are NOT carriers unless the information provided indicates otherwise. A1 A2 II B1 B2 B3 B4. B5 B6_ II C1. C2 C3. C4. C5 IV D1. D2, D4 . D5 Individuals C2 and C3 are considering having additional children. However, having already had a child with this disorder, they visit a genetic counselor to determine what the probability is that their future child would have the disorder. If C2 and C3 have another…

A backyard homesteader that wants to expand the amount of cute duck breeds. They know the f gene codes for feather coloring (black feathers (F) are dominant to white feathers (f)) while the b gene codes for feet color (grey feet (B) are dominant to orange feet (b)). The homesteader crosses a super fertile heterozygous wild-type duck that has black feathers with grey feet (FfBb) with a homozygous recessive duck with white feathers and orange feet (ffbb). This produces 100 offspring.  2. Which are parental phenotypes? (2 answers)
