- Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?In a certain animal, black coat (B) are dominant to white coat (b). In a genetic cross of two animals that are heterozygous for coat color, what is the probability of having white coat? Write in fraction formIn the shorthorn breed of cattle, The red and white coat colors are codominant with each other with the resulting hit rosagas condition being roan. A breeder has some white, some Roan, and some red cattle (female) And only one round bull (male).  A. What color cow would be bread to the ro bowl to guarantee the best chance of having white offspring? B. What is the probability of a red cow cross with the Roan bull resulting in a white half? explain by using parent and possible offspring genotypes.  C.

Thank you!. A corn geneticist has three pure lines of genotypes a/a ; B/B ; C/C, A/A ; b/b ; C/C, and A/A ; B/B ; c/c. All the phenotypes determined by a, b, and c will increase the market value of the corn; so, naturally, he wants to combine them all in one pure line of genotype a/a ; b/b ; c/c. a. Outline an effective crossing program that can be used to obtain the a/a ; b/b ; c/c pure line. b. At each stage, state exactly which phenotypes will be selected and give their expected frequencies. c. Is there more than one way to obtain the desired genotype? Which is the best way?Assume independent assortment of the three gene pairs.
