Question

A rose has a phenotype ratio of 3:1 where red roses are dominant over white roses. Out of a total of 4 roses, how many of the roses are red? 1 2 3 4

Answer 1

Answer: 3

Step-by-step explanation:

Since the phenotype ratio is 3 : 1, where red Roses are dominant over white roses, the ratio of red will be 3 while the white will be 1

Finding the value of the two roses will be;

3 + 1 = 4

For red roses,

3/4 × 4 = 3

For white rose,

1/4 × 4 = 1

Therefore, 3 of the red roses are there.
