What causes the difference between the mRNA molecule in different tissue is PRE mRNA SPLICING. Splicing refers to the modification of the nascent precursor messenger RNA.The splicing of a mRNA molecule occur in several steps and the steps are catalyzed by ribonucleoproteins. During splicing, the introns sections are removed and the remain sections called exons are joined together.

In humans, syndactyly (webbed digits) is inherited by possession of a dominant allele (S). If a man who is homozygous and normal
____ [38]

Answer:

The % of children with webbed digits is 50%

Explanation:

Given -

Syndactyly or webbed digits are due to the presence of  a dominant allele (S). Then the allele for normal digits would be represented by allele "s"

A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"

If we cross Ss and ss , then the following offspring are produced -

Ss * ss

Ss, Ss, ss, ss

Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is 50%
