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.

<h3>Explanation:</h3>

Following a cross between <u>Ttbb</u> and <u>ttBb</u>, the resulting offspring would be:

TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb , TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb

To have a clearer idea, see the attached image.

Of the 16 possible combinations from this dihybrid cross, there will be:

4 tall plants with blue flowers

4 tall plants with white flowers

4 short plants with blue flowers

4 short plants with white flowers

There are 4 possible genotypic recombinations that would yield short plants with white flowers out of a possible 16, so the chance that the offspring will be short with white flowers would be 4/16 which is 1/4 or 25%
