During the early days of deciphering the human genome, scientists were surprised to find that the number of genes appeared to be
Alekssandra [29.7K]

Given what we know, we can confirm that the aspect of nucleic acids and transcription that can help explain this discrepancy is that of alternative splicing.

<h3>Alternative Splicing.</h3>
  • This process allowed the cells to use a single gene for the creation of various proteins.
  • This process includes the separation of RNA at splicing sites to create new versions of the mRNA strand.
  • This helps to increase the diversity of mRNA's available and create more proteins.

Therefore, given that alternative splicing allows the cells to create multiple forms of distinct proteins from a single gene, this allowed our organisms to develop the vast number of proteins we use, without the need for a much larger genome.

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this could be an example of ___________. H
givi [52]

Answer:

Incomplete dominance

Co-dominance

Explanation:

Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.

One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.

Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.
