Summary Introduction
To explain: The expected ratio of offspring, if a heterozygous
Introduction:
A single trait (monohybrid) cross includes the cross in a plant like a pea where the trait is chosen as “dominant one” includes the purple color of the flower depicted as

How would I figure this out using a punnett square?
Next, you perform a cross of two heterozygous, red-eyed flies. They have 100 offspring. How many of these offspring do you predict will have red eyes? Show your work using a Punnett square. [Use letters R and r to designate the alleles].
You cross a pea plant with the genotype AaBbCcDd with a pea plant that is AABbCCdd. What is the probability that you get an offspring with the genotype AaB_C_dd? Show your work
In tomatoes, red fruit is dominant to yellow fruit, and purple stems are dominant to green stems. The progeny from one mating consisted of 305 red fruit, purple stem plants; 328 red fruit, green stem plants; 110 yellow fruit, purple stem plants; and 97 yellow fruit, green stem plants. What were the genotypes of the parents in this cross? Explain how you arrived at your answers.
