Solution:
Given, in a cross between two F1 heterozygous tall plants, the F2 progeny consisted of tall and dwarf plants in the ratio 3 : 1.
Let T represent the allele for tallness and t represent the allele for dwarfism.
Thus, the genotype of the F1 heterozygous tall plants can be represented as Tt.
The cross between two F1 heterozygous tall plants can be represented as:
Tt x Tt
| |
Tt Tt
| |
TT Tt

Tt tt
The F2 progeny consisted of tall and dwarf plants in the ratio 3 : 1.
Thus, the probability of getting a tall plant is 3/4 and the probability of getting a dwarf plant is 1/4.
We need to find the probability that out of 7 plants chosen at random, 4 would be tall and 3 would be dwarf.
This can be calculated using the binomial probability formula:
P(X = k) = (n C k)pk(1 - p)n-k
Where,
n = total number of trials = 7
k = number of successes = 4
p = probability of success = 3/4
q = probability of failure = 1/4 = 0.25
P(X = 4) = (7 C 4)(3/4)4(1/4)3
= (35)(27/256)(1/64)
= 0.1748 (approx.)
Therefore, the probability that out of 7 plants chosen at random, 4 would be tall and 3 would be dwarf is 0.1748 (approx.).
