Use your Punnett Square: Child 1 and Child 2 inherited the genotype predicted to be present in 50% of the offspring, which means they will have freckles. What is their genotype?

Note about the question:

I failed to find the complete question, but I am going to give two possible options about the Punnett square that might be useful. In any of the cases, the answer is the same.

The children´s genotype is heterozygous for the freckles trait, Ff.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
