Genetics Fun with Punnett Squares!

Which Punnett square represents the correct way to set up the cross RRYy ´ RrYY?

A punnet square is a diagram that is used to predict an outcome of a particular cross or breed experiments. So based on the following data you have given, which Punnett square should we use?

Answer: C

The correct Punnett square representing the cross RRYy ´ RrYY would be option C, which is shown in mc012-3.jpg. It shows the combination of alleles in a clear and organized manner to predict the offspring's genotype.

When setting up a Punnett square for a genetic cross, it's important to understand the dominant and recessive traits involved. In this case, round seeds and yellow seed color are dominant over wrinkled seeds and green seed color.

The letters R and Y represent the dominant alleles for round shape and yellow color, while r and y represent the recessive alleles for wrinkled shape and green color, respectively. When we cross RRYy with RrYY, the possible combinations of alleles in the offspring can be predicted using the Punnett square.

The Punnett square in option C (mc012-3.jpg) correctly shows the combination of alleles from the parents RRYy and RrYY. The horizontal axis represents the alleles from the first parent (RY, RY, rY, rY) and the vertical axis represents the alleles from the second parent (RY, Ry, RY, Ry).

By analyzing the Punnett square, we can see the possible genotypes of the offspring, which can help in understanding the inheritance pattern of traits in genetics. It's a fun and visual way to explore genetic probabilities and outcomes!
