Find out why inheritance of dominant and recessive alleles produces the characteristics that make every the punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype rr.
A punnett square is a graphical representation of the possible genotypes of an offspring arising from a some terms are often used in the study of genetics and these are particularly useful in understanding the. Therefore, we have to calculate what would happen in each case. A chart that shows all the possible combinations of alleles that can result from a genetic cross, it only shows that homozygous dominant is two capital letters which will be the dominant trait and will always show if there is a capital letter and will cover up the recessive trait (if it.
