Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

jekas [21]

Answer:

The correct answer would be - 100% chances that their child will not have the disease.

Explanation:

Cystic fibrosis is one of the lethal diseases that inherited in an autosomal recessive manner. The Autosomal recessive pattern takes place when the defected gene present in the autosome chromosomes of an individual and only exhibits when both copies of recessive gene present.

The affected person must have two copies of the recessive allele - cc and the gamete he will produce will be - c only, however in the normal person, both copy of allele must be dominant - CC and will produce the gamete - C only.

Then from Punnett square :

                                            C       C         (normal parent)

(affected parent)   c         <em> Cc      Cc</em>

                                c          <em>Cc     Cc</em>

By this, it is established that in case all the offspring will have one copy of dominant and one copy of recessive gene which means 100% chances of carrier child.

Thus, the correct answer would be - 100% chances that their child will not have the disease.
