Alja [10]2 years ago
4 0

Answer:

1. 1/2

2. 1/2

3. 1/4

Explanation:

Let the allele for freckles be A or a while that of dimples be B or b.

A person without freckles but heterozygous for dimples = aaBb

A person who has freckles (whose mother has no freckles) but no dimples = Aabb

      aaBb    x    Aabb

Offspring

4 AaBb - freckled and dimpled

4 Aabb - freckled and non dimpled

4 aaBb - non freckled and dimpled

4 aabb - non freckled and non dimpled

1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2

2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2

3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4

DiKsa [7]

Answer: The question is incorrect, below is the correct question

Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?

The correct answer to the question is option D

mtDNA (mitochondrial DNA) analysis

Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.

There are several methods of DNA fingerprinting as outlined in the options given with the question.
