If the bicuspid (mitral) valve is not fully closing, does pulmonary circulation increase, decrease, or not change?
elena-14-01-66 [18.8K]

Answer: Decrease

It will decrees because required volume of blood will not be   emptied into the pulmonary circulation  to reach the lung for oxygenation. Rather blood flows back into the  Right  atrium ,(regurgitation,) through the these valves   during ventricular contraction ( systole)of the Right Ventricle instead to the pulmonary circulation which  reduces blood flow leading  to volume overload  in  the heart. Eventually this  affects systemic circulation,

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t
Gelneren [198K]

Answer:

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

  • A (colored seed) is dominant over a (colorless)
  • Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).

  • The homozygous recessive can only produce <em>a wx </em>gametes.
  • The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>

<u>The possible offspring resulting from the combination of those gametes is:</u>

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).
