To avoid self-fertilization in his pea plants, Mendel had toa. spray the plants with a chemical that damaged thepollen.b. remove the anthers from immature flowers.c. grow the plants in a greenhouse that did not containpollinators (e.g., bees).d. do all of the above.
Mendel's pea plants were a good choice for studying heredity, because:
a) They have lots of easily observable traits that vary in an either-or manner.
b) Their mating is uncontrollable.
c) There are separate male and female plants.
d) The plants are incapable of cross-pollination.
Figure 4 shows the hybridization process between plant P and Q.
a) Determine the sterile hybrid plant and the fertile hybrid plant.
b) What is process A?
c) State the chromosome number for the fertile hybrid plant.
