Answer :
50% is the expected genotypic ratio among the offspring.
In this scenario, the heterozygous female is crossed with a recessive male, thus we may deduce from the Punnett square that only half of all children would have blue eyes.
The genotype Bb must be a brown-eyed male whose mother was blue-eyed, where B denotes brown-eye color and b signifies blue-eye color. When a guy with this genotype marries a woman with blue eyes, the children are 50 percent blue and 50 percent brown. A Punnett square is a graphical representation of an offspring's probable genotypes as a result of a certain cross or breeding event. Understanding the genetic makeup of the parents is required to create a Punnett square. In a tabular structure, the countless potential combinations of their gametes are enclosed.
The underlying premise is that each feature is determined by a separate gene locus and that distinct traits differ independently from one another. While this is true for many important characteristics, there are numerous exceptions, particularly when selecting traits for plant or animal breeding.
As a result, the right answer is '50%.'
