Answer:
1/4
Explanation:
A heterozygous woman for both traits (RrFf) marries with a man with no freckles (ff) who can't roll his tongue (rr).
The cross is: RrFf X rrff.
The woman can produce the gametes <em>RF, Rf, rF </em>and <em>rf</em>
The man can only produce <em>rf </em>gametes.
<u>The possible offspring that can arise from the combination of those gametes is:</u>
- 1/4 RrFf Freckled, tongue-rolling
- 1/4 Rrff Freckled, unable to roll tongue
- 1/4 rrFf Not freckled, tongue-rolling
- 1/4 rrff Not freckled, unable to roll tongue
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
