Suppose that you wanted to test Mendel's results using the same species and varieties he used. Further, suppose that you bred one type of pea plant to have purple-flowers and wrinkled seeds with genotyps Pprr, and another type to have white flowers and round seeds with genotype ppRr.
What proportion of the offspring from this cross would you predict, on average, to have genotype pprr?
On average, what proportion of the offspring from such a cross would you predict to have purple flowers, regardless of seed shape?

You decide that you want to replicate some of Mendel’s original results. You begin your experiment with plants that have true breeding traits, one set of plants that have purple flowers and round seeds, the other with white flowers and wrinkled seeds. You do a cross and the progeny (F1 generation) are all purple flowering and produce round seeds. What is the probability that a cross between two F1's will yield offspring that are white and with wrinkled seeds? Seed...

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

In Mendel's pea plants, the allele for purple flowers (P) is dominant to the allele for white flowers (p). You cross two pea plants that are heterozygous for the flower color trait and obtain 36 peas. When you plant these peas and grow them long enough to see their flowers, you find that 25 of them have purple flowers and 11 of them have white flowers. (a) For this cross, what are the expected values for each phenotype? (1 point)...
