WebNov 4, 2024 · The Punnett square from this configuration is below. Here we see that there are three ways for an offspring to exhibit a dominant trait and one way for recessive. 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. B. WebThe Punnett square is a valuable tool, but it's not ideal for every genetics problem. For instance, suppose you were asked to calculate the frequency of the recessive class not for an Aa x Aa cross, not for an AaBb x AaBb cross, but for an AaBbCcDdEe x AaBbCcDdEe cross. If you wanted to solve that question using a Punnett square, you could do it – but …
