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.
Crossing over is the exchange of chromosome segments between non-sister chromatids during the production of gametes.
Answer:
The correct answer is - red blood cells are biconcave.
Explanation:
RBC or the red blood cells are the cells that play an important role by many means such as transferring nutrients, hormones, and oxygen throughout the body. The transfer of the oxygen is accompanied by the help of hemoglobin, a protein that carries oxygen and takes it to the different sites in the body.
These cells are biconcave which helps them to provide more cell surface area to grab or attain maximum space for hemoglobin which helpful in oxygen significant oxygen-carrying capacity of Red blood cells.
Thus, the correct answer - red blood cells are biconcave.
