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.
A dominant trait is represented by a capital letter
Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering.
