If the parents for the P generation are RR and Rr, then the F1 will be: Question 6 options: all Rr all RR ½ Rr and ½ rr ½ RR and ½ rr ½ RR and ½ Rr
Question
If the parents for the P generation are RR and Rr, then the F1 will be:
Question 6 options:
all Rr
all RR
½ Rr and ½ rr
½ RR and ½ rr
½ RR and ½ Rr
Solution
The P generation parents are RR (homozygous dominant) and Rr (heterozygous).
When these two mate, the possible combinations for the F1 generation are:
- RR (from the first parent's R and the second parent's R)
- Rr (from the first parent's R and the second parent's r)
So, all offspring in the F1 generation will either be RR or Rr.
Therefore, the correct answer is "½ RR and ½ Rr".
