Given,

Dominant - Long wings and Gray color

Recessive - Short wings and Brown color

Let the allele for long wings be "L" and the allele for short wings be "l".

Let the allele for brown color be "g" and allele for gray color be "G"

Genotype of parents

LlGg

Gametes of the parent

LG, Lg, lG, lg

Dihybrid cross is between LlGg and LlGg

The offspring produces will be as follows -

LG        Lg         lG         lg

LG LLGG LLGg LlGG LlGg

Lg LLGg LLgg LlGg Llgg

lG LlGG LlGg llGG         llGg

Restriction enzyme HinfI cleaves a five nucleotide DNA sequence GA(A/T)TC. The ambiguity in the central position - (A/T) - means
Afina-wow [57]

Answer:

C) 2.0 kb

Explanation:

It is given that out of the 4 nucleotides A, T, C & G each one has equal probability to occur at any position on the DNA molecule which simply means that the probability of occurrence of any nucleotide at a position is 1/4.

Also, it is given that probability of occurrence of either A or T at 3rd position is equal which means that the probability at that particular position will be 2/4 = 1/2.

Now, GA(A/T)TC is the DNA sequence where Restriction enzyme HinfI cleaves so the total probability of an average HinfI cleavage fragment will be = 1/4 x 1/4 x 1/2 x 1/4 x 1/4 = 0.00195 = 0.2 i.e. 2 kb.
