Answer:

1/2 IAIB, 1/2 IBIB (es decir, 50% IAIB  y 50% IBIB)

Explanation:

El grupo sanguíneo está determinado por un gen que posee tres diferentes variantes o formas alélicas:

alelo A: IA

alelo B: IB

alelo O: IO

Los alelos IA y IB son codominantes entre sí, es decir, un portador de ambos alelos será de grupo sanguíneo IAIB. Por otra parte, tanto el alelo IA como el alelo IB son dominantes del alelo IO recesivo. En este caso, el cruzamiento entre un individuo heterocigota IAIB con un individuo homocigota IBIB dará como resultado una descendencia 1:1 de heterocigotas IAIB y homocigotas IBIB (es decir, 50% IAIB  y 50% IBIB), ya que la madre producirá ambos tipos de gametos en proporciones equivalentes (1/2 IA  y 1/2 IB), mientras que el padre sólo producirá gametos IB.

As mean arterial pressure increases, the ________, informing the medulla oblongata that blood pressure has indeed increased.
finlep [7]

As mean arterial pressure increases, <u>the frequency of action potentials from the </u><u>baroreceptors</u><u> increases,</u> informing the medulla oblongata that blood pressure has indeed increased.

  • Special receptors called baroreceptors monitor variations in your blood pressure.
  • The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
  • Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
  • The brain interprets the information that the baroreceptors send as a rise in blood pressure.
  • The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.
