Need help with Dihybrid cross
Sal is a wonderful pea plant that has green, wrinkled seeds. What is its genotype? What are all the possible gametes it could make? Remember that you now have TWO traits, so each gamete should have TWO alleles, one for each trait. Sally is another pea plant in your garden that yellow, round seeds. We will assume that Sally is homozygous dominant for both traits. What is its genotype? What are all the possible gametes it could make? What are the genotypic and phenotypic ratios of Sal and Sally’s offspring using a punnet square.
You plant two of Sal and Sally’s offspring and name them Sandra and Sandor. You then perform a cross of Sandra and Sandor. Fill in Punnett square below to figure out what the genotypes of Sandra and Sandor’s offspring will be. Then copy and paste the Punnett square below into your lab write up.
What are the genotypic and phenotypic ratios expected for the offspring of this cross?
