As described above, the condition will lead or cause the lung tissue to be less elastic. That being said, the lungs will be limited due to its stiffness. This will lead to decreased lung capacity as well as decreased vital capacity.

Answer:
Option B, Rr pp × rr Pp
Explanation:
Given 
Walnut Comb is produces when  one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*
Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp
Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second  - rr P*
Single comb - two recessive alleles are present at the first and the second locus  - rrpp
Parent are rose combed and pea combed
For being rose genotype must be R* pp 
and for being pea combed genotype must be rr P*
Rr pp x rr Pp
will  produce 
Walnut comb  with genotype Rr Pp
Single comb  with genotype rrpp
and pea comb  with genotype rrPp
Hence, option B is correct

It would be expierments and it would be change per time or it could also be change per minute
