Although the number of genes in the human genome is surprisingly low compared to less complex organisms, the number of possible
Effectus [21]

Answer:

alternate arrangements of exons from a primary transcription.

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Although, the number of genes contained in the human genome is surprisingly low in comparison with less complex organisms such as bacteria, protozoa, salmonella, etc.

However, the number of possible products from those genes is greatly amplified by alternate arrangements of exons from a primary transcription.

An exon refers to the coding portion of a gene that contains the information required for transcribing and translating (encoding) the final part of a mature RNA, after one or more DNA sequences (introns).

Simply stated, an exon is a nucleotide sequence in DNA and RNA used for encoding a part of the final mature RNA.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

<u>r</u>                       rr                  rr

Genotype of the mother with freckle trait is rr. This means that it is a recessive  trait.

Genotype of of the father having clear facial skin is Rr, showing that it is a dominant trait. There can be two genotypes for this trait that is Rr and RR.

When these parents are crossed, they produce 50% offsprings with the freckles trait (rr) and 50% with clear facial skin ( Rr).

Therefore, the likelihood of the first child with freckles is A
