Answer:
C) 50%
Explanation:
Let the homozygous recessive organism be rr
Let the heterozygote be Rr
If both organism crosses together: Rr × rr
= we have ( Rr, Rr, rr, rr) as their offspring.
The question says; what is the chance of producing an offspring with the homozygous recessive phenotype?
From above, the chance of producing an homozygous recessive is 50%.
i.e (2/4) × 100%
=(1/2) × 100%
= 50%
