1. A woman with $X$-linked color blindness (an $X$-linked recessive trait) and Turner syndrome had a color-blind father and a mother without medical records of having any of those two conditions (5 points).

Question

Accepted Answer

∻Answer∻ ⚹ The woman inherited X-linked color blindness from her color-blind father and Turner syndrome likely due to a nondisjunction event during gametogenesis in one of her parents. ⚹ ∻Solution∻ ‖ a ⋮ X-linked color blindness inheritance: Since the woman has X-linked color blindness and her father is color-blind, she must have inherited the affected X chromosome from him. ‖ ‖ b ⋮ Turner syndrome inheritance: Turner syndrome (45,X) occurs when an individual has only one X chromosome. This can happen due to nondisjunction during gametogenesis in either parent, resulting in a gamete that lacks an X chromosome. ‖ ∻Key Concept∻ ⚹ Inheritance of X-linked recessive traits and Turner syndrome ⚹ ∻Explanation∻ ⚹ A woman with X-linked color blindness must have inherited the affected X chromosome from her father. Turner syndrome arises from a nondisjunction event that leads to the presence of only one X chromosome in the affected individual. ⚹◊What are the chances of a woman inheriting both X-linked color blindness and Turner syndrome if her father is color blind and her mother has no medical records of either condition?⍭ Generate me a similar question◊
