Answer:

If the question is referring to Mendel's postulates, all options are correct

Explanation:

Gregor Mendel discovered that certain components he called UNIT FACTORS determine inheritance. This unit factors were later described to be genes in modern genetics. He discovered that an organism receives two forms of this unit factors from each parent, which he called ALLELES. In his experiments, he observed that one of the pair of alleles have the ability to mask the expression of its variant pair. He called the allele that masks, DOMINANT allele while the allele that is masked, RECESSIVE allele.

During his cross experiment, he discovered that the alleles of a gene (unit factor) separates into gametes, he called this LAW OF SEGREGATION. He notably discovered in his cross involving two different characters that the segregation of the alleles of one gene into gametes does not influence the segregation of the alleles of the other gene. He termed this his LAW OF INDEPENDENT ASSORTMENT.

<span>d.      </span> The percentage of mice that are heterozygous: _48%________

<span>e.      </span>The percentage of mice that are homozygous recessive: __36%_______

 

Let us assign the dominant allele (that of brown hair) letter R while

We assign the recessive allele (that of white hair) letter r

We then note down the Hardy-Weinburg equation p2 + 2pq + q2 = 1

Brown fur population (p2 + 2pq) = 64% = 0.64

White fur population (q2) = 36% = 0.36

Then we also remember that the frequencies of both allele add up to 1 (p + q = 1);

Therefore q = ü.36 = 0.6

P = 1 – q = 1 – 0.6 = 0.4

The heterozygous population will be 2*0.6*0.4 = 0.48 =  48%

Homozygous domain population will therefore be (64% - 48%) = 16%

spayn [35]

The body part the medical artist should draw smallest is the arm.

<h3>What is a homunculus?</h3>

A homunculus can be defined as a graphical representation a very small (miniature) human being or humanoid creature, especially from which a fetus developed from.

In Medical field, the arm of a homunculus are generally drawn smallest in relation to the size devoted to it in the somatosensory cortex.

<h3>What is the somatosensory cortex?</h3>

The somatosensory cortex refers to a region of the brain which is saddled with the responsibility of receiving and processing sensory information that are obtained from various body parts such as:

  • Pain
  • Touch
  • Temperature
