the formula for number of gametes is 2n
where n is number of unlinked gene pairs
here n is 5
so 25 =32

Complete a dihybrid cross between a pea plant (plant 1) with white flowers and wrinkled seeds with a plant (plant 2) with purple flowers and round seeds. Fill in the Punnett square between Plant 1 and Plant 2. Plant 2 is heterozygous for flower color and homozygous for seed color. What are the phenotypic ratios of the F1 generation? Phenotypes: purple flowers with round seeds: purple flowers with wrinkled seeds: white flowers with round seeds: white flowers with wrinkled seeds:...

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 this tutorial you will examine dihybrid crosses: crosses
where alleles at separate loci assort independently into gametes at
meiosis. You will also use logic to determine unknown genotypes,
phenotypes, and genetic ratios from given data.
Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele...

1. A pea plant with round seeds is crossed with a pea plant that has wrinkled seeds. For the cross, indicate each of the following: a) the genotype of each of the parents if the dominant phenotype is heterozygous. b) What gametes will each parent produce c) if two round plants from the Fl generation are crossed, what would be the resulting genotypes and phenotypes of the F2 generation? Provide the Punnett square as well as your answer below.

genetic cross question
In a trihybrid cross in garden pea plants that differ in plant height (tall is dominant to dwarf), flower color (purple is dominant to white), and seed color (yellow is dominant to green), what is the probability of getting a tall plant with purple flowers and green seeds in the F2 generation.
