In plants tall T is dominant to short t .perform the following cross Tt x Tt what is the probability of producing a short plant

25% or 1/4 chance

Explanation:

When crossing these two heterozygous parents, you will get the phenotype 3:1. This means...

75% chance of plant being tall

25% chance of plant being short

Since T is dominant and we are using simple Mendelian inheritance, the heterozygous offspring (Tt) will be tall as well.

This means there is a 25% or 1/4 chance of the plant being short.

~Punnett square and work below for you.

answer; i believe the correct answer is (sporophyte);

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.
