This is determined through a punnett square, which shows the possible combinations of the parents' alleles It works on the principles of mendelian genetics, offering visual representation and probabilistic understanding of genetic inheritance, particularly for traits linked to the sex chromosomes x and y. According to this punnett square (table above), the son of a woman who carries the color blindness trait and a male with normal vision has a 50% chance of being colorblind Summary each individual has two sex chromosomes Females have two x chromosomes (xx), while males have one x chromosome and one y chromosome (xy) Includes examples and practice problems for high school science.
In this problem, a male with colorblindness marries a female who is not colorblind but carries the (b) allele Using a punnett square, determine the genotypic and phenotypic probabilities for their potential offspring.
