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.

Skin cells and heart cells are so different because they O use different genetic codes. have different chromosomes. O have different genes. O express different subsets of genes. O have different promoter sequences.
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.
