The punnett square is a square diagram that is used to predict an outcome of a particular cross or breeding experiment. 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. Punnett squares are used to figure out the possible gene combinations from a genetic cross. The offspring of a monohybrid cross is called monohybrids.
A punnett square is a chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents. It is important that you understand the steps in the extraction procedure and why each step was necessary. In this example, both parents are heterozygous for flowercolor ( bb ).

They are useful as they can predict the genetic probability of a particular phenotype arising in a couple's offspring. Some of the terminology you'll come across when dealing with genetics can be confusing, so we'll start by defining some terms and then put them all together to see how they relate. It is important that you understand the steps in the extraction procedure and why each step was necessary. 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.
