Analysis of the nucleotide sequences of genes coding for phytochrome pigments suggest that the ancestors of angiosperms were adapted for survival in .

c. shady forests.

Explanation:

According to a different source, these are the options that come with this question:

a. freshwater aquatic environments.

b. sunny, xeric habitats.

c. shady forests.

d. habitats with very cold winters.

e. oceans.

Angiosperms are plants that have stems, roots and leaves. Moreover, these plants have seeds in a flower. Usually, angiosperm eggs are fertilized through pollination in a flower. Flowers have both male and female reproductive organs. Based on the analysis of the nucleotide sequences of genes, it appears that the ancestors of angiosperms were adapted for survival in shady forests.
