**Problem: Genetics of Colorblindness and Cleft Chin**A woman without red-green colorblindness and with a normal chin, whose mother was colorblind, marries a cleft-chinned, non-colorblind man whose mother had a normal chin. Recall that red-green colorblindness is sex-linked recessive, but mid-chin fissure (cleft) is autosomal dominant. What are the expected phenotypic ratios of the children? Show your work.**Background Information:**- **Red-Green Colorblindness:** - Inherited in a sex-linked recessive manner located on the X chromosome. - Males having one allele (XcY) express the trait due to only one X chromosome. - Females express the trait when homozygous recessive (XcXc).- **Cleft Chin:** - An autosomal dominant trait. - Expressed in individuals with at least one dominant allele (C) for cleft chin (CC or Cc).**Phenotypic Ratios Calculation:**1. **Parental Genotypes:** - **Mother (woman):** - Non-colorblind (XNXn) [since her mother was colorblind, she must be a carrier] - Normal chin (cc) - **Father (man):** - Non-colorblind (XNY) - Cleft chin (Cc) [since his mother had a normal chin, he carries one recessive allele]2. **Punnett Square Analysis:** **Colorblindness:** - Maternal alleles: XN, Xn - Paternal alleles: XN, Y - Offspring combinations: XNXN, XNXn, XNY, XnY **Chin Type:** - Maternal alleles: c, c - Paternal alleles: C, c - Offspring combinations: Cc, Cc, cc, cc3. **Resulting Phenotypic Ratios:** - **Non-colorblind & Cleft Chin (Female):** XNXN Cc, XNXn Cc - **Non-colorblind & Normal Chin (Female):** XNXn cc - **Colorblind & Cleft Chin (Male):** XnY Cc - **Colorblind & Normal
