The correct answer is: prefrontal cortex

Synaptogenesis or formation of synapses begins about the 23rd week of gestation. The peak of synapse production is achieved at different periods. The massive overproduction of synapses that occurs in early childhood is followed by a gradual reduction of them also known as "synaptic pruning".  “Synaptic pruning” happens during childhood, and during adolescence.

The brain continues to grow and develop, but the overall number of neurons and synapses are reduced by up to 50%. This is process that is experience driven: unnecessary neuronal structures are removed and replaced by more complex and efficient structures, that are more required to the demands of adulthood.

Amiraneli [1.4K]

Probability that the child would be homozygous for the g542x allele 0.00

<h3>why the probability is nil?
</h3>
  • The kid cannot be homozygous for the G542X gene since only the mother has it; the father, on the other hand, has a mutant dF508 allele and so cannot pass on a copy of mutant G542X = never homozygous recessive child.
  • A kid must have the G542X allele from both parents in order to be homozygous for the G542X allele. Because only the mother possesses the G542X gene, the child's chances of being homozygous for the G542X allele are 0.00
<h3>When offspring show a blend of the parents traits one allele is dominant over the other?</h3>
  • At the point when one allele is predominant over another, posterity show a mix of guardians' qualities.
  • The heterozygous aggregate in complete predominance is tracked in the middle of between two homozygous aggregates. A heterozygous individual showcases qualities of the two guardians in the event of codominance.
