In pea plants, red flowers and round pollen are known to be recessive traits. In a dihybrid cross experiment, lots of plants with red flowers and round pollen are found in the F2 generation. How is this possible?
The genes for flower color and pollen shape are linked.
a) Multiple genes control the traits for flower color and pollen shape.
b) The genes for flower color are linked to pea shape, but not pollen shape.
c) The genes for flower color and pollen shape are found on different d) chromosomes.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
