Two pink flowering plants are crossed. The offspring produce flowers as follows: 25% Red, 25% White and 50% pink. What pattern of inheritance is shown by the flower color in these plants?

Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance in which two alleles of a gene is neither dominant nor recessive over one another, hence, they form an intermediate third phenotype, which is a blending of both phenotypes.

In this question, the allele for red flower (R) in a certain flowering plants is INCOMPLETELY DOMINANT over the white allele (r). Hence, a pink (Rr) flower color is formed, which is heterozygous. However, if two pink flowering plants are crossed, the offspring produce flowers as follows: 25% Red (RR), 25% White (rr) and 50% pink (Rr). This depicts INCOMPLETE DOMINANCE.

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.
