Punnett Square (P-Square) Calculator Punnett square is a chart used by geneticists to show all possible allelic combinations of gametes in a cross of parents with known genotypes. One parent is homozygous for a certain trait and the other is heterozygous. A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (tan is the recessive color). Again we do this be taking a letter from the left & matching it with a letter from the top. The same process can be applied to other modes of inheritance, such as co-dominance and incomplete dominance. Do the Punnett square. HOW TO SOLVE CHI-SQUARE PROBLEMS Chi-Square = sum of the (observed-expected)2 / expected The problem is usually figuring out the expected.

Can a color blind female have a son that has normal vision? Color blindness is caused by a sex-linked recessive allele. To answer these questions, geneticists use a simple tool called a Punnett square. This means that there is a 75% probability that an offspring will have the dominant trait and a 25% probability that an offspring will have a recessive trait. Making Predictions: If the genotypes of parents are known, it is possible to make predictions about the phenotype(s) of their offspring.
