What two essential criteria must be met in order to execute a successful mapping cross?
What are monohybrid crosses? Is it possible to make a cross in which only one single character is actually involved, or is it just that one single character is being analyzed and the others are being ignored?
Using the genotypes of this cross, can you give a general definition fora test cross?

- You want to determine whether genes a and b are linked. What cross would you use and why? How would this cross tell you if they are linked?arrow_forwardFigure 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?
