Why human with heterozygous genotype will have the dominant phenotype?
AnnZ [28]

A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.

  • Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
  • When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
  • When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
  • When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.

Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

If intrapulmonary pressure was 760 mm hg, what would you expect the intrapleural pressure to be?
Natasha_Volkova [10]
<h3><u>Answer;</u></h3>

756 mm Hg

<h3><u>Explanation;</u></h3>
  • Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae. This pressure changes during different phases of breathing.
  • <em><u>Due to certain characteristics of the lungs, the intrapleural pressure is always lower than, or negative to, the intra-alveolar pressure. It  remains approximately –4 mm Hg throughout the breathing cycle.</u></em>
  • <em><u>Therefore; if the intrapulmonary pressure was 760 mm hg then the intrapleural pressure will be (760 -4) mm Hg, that is 756 mm Hg</u></em>
