Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.

Where are the effects o f a dominant allele seen?

it is present (shown) whenever it is present ( see Punnett Square) it will overthrow a recessive allele as long as it is there. it's effect is that you will get a certain trait for that allele. A Punnett Squar will help you the most.

What is a chart that shows all possible allele combination resulting from a genetic cross?

A Punnett square is a diagram used to predict the possible genotypes of offspring in a genetic cross. It displays all possible combinations of alleles that parents can pass on to their offspring.


How do you find the gene combination on a punnett square?

To find the gene combination on a Punnett square, you need to determine the possible combinations of alleles that can be inherited from each parent based on their genotypes. Then, you can fill in the Punnett square boxes with the possible allele combinations to see the potential genotypes of their offspring.
