The photos above show flowers from Arabidopsis plants. One plant is wild-type (unmutated); the other carries a mutation in one of its ABC floral identity genes. This mutation causes sepals and petals to form instead of stamens and carpels. Refer to Figure 10.8 to decide which gene (A, B, or C) has been inactivated by the mutation.

Many farmers are worried about the decreasing genetic diversity of plants associated with generations of artificial selection and inbreeding. Why is limiting random sexual reproduction of food crops concerning? Mutations during asexual reproduction decrease plant fitness Consumers do not trust identical-appearing produce Larger portions of the plant populations are susceptible to the same diseases Spores are not viable in an agricultural setting.
The photos below show flowers from two Arabidopsis plants. The plant on the left is wild-type (unmutated); the other carries a mutation that causes its flowers to have sepals and petals instead of stamens and carpels. The mutation inactivated one of the plant's ABC floral identity genes. Refer to Figure 10.8 and decide which gene (A, B, or C) has been inactivated.
