The phenotype and percentage are
R r
R | RR (25%) | Rr (50%) |
r | Rr (50%) | rr (25%)|
How can find the phenotype and percentages?
RR Offspring:
Phenotype: Dominant (expresses the R allele)
Percentage: 25%
When both parents contribute the dominant R allele, the offspring inherits two R alleles, resulting in the dominant phenotype.
Rr Offspring:
Phenotype: Dominant (expresses the R allele, but may also carry the r allele)
Percentage: 50%
This is the most likely outcome, as each parent has a 50% chance of passing on the R allele. Offspring with Rr genotype will still express the dominant phenotype, but they are carriers of the recessive allele.
rr Offspring:
Phenotype: Recessive (expresses the r allele)
Percentage: 25%
When both parents contribute the recessive r allele, the offspring inherits two r alleles, resulting in the recessive phenotype.
