a Punnett square summarizes how the processes of meiosis and fertilization contribute to inheritance of different alleles of a gene. So one major advantage is it can help determine certain things about a child by looking at the dominant and recessive genes and gives a percent of how likely they are to get that thing for example a punnet square may show what color a child’s eye color is likely to be upon birth
One advantage of Punnett squares as a model of inheritance is that a Punnett square summarizes how the processes of meiosis and fertilization contribute to inheritance of different alleles of a gene.
