This is a modified question from the textbook, Campbell Biology in Focus (3rd edition), question #5 on page 256. A man with normal vision marries a woman with normal vision whose father was red-green color-blind (a recessive, sex-linked condition). Assuming that the woman's mother had normal vision and did not carry the recessive gene, what is the probability that the married couple will have a color-blind daughter? That their first son will be color-blind? That their second son will be color-blind? Include Punnett square for each question in your answer. You may find the below diagram helpful (the orange square means the individual has the phenotype of color-blindness, while the beige means the individual is a carrier of the mutated color-blind gene where XN and Xn represent dominant and recessive allele, respectively).

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
