The odds are astronomical for a father with AB(IV) to have an O(I) child. The only possible way for this phenomenon to occur is if there was a nondisjunction in the ovogenesis for the 9th chromosome and the father also had a nondisjunction for the same chromosome(A sperm cell with no 9th chromosome fertilized an ovum with two 9 chromosomes).

A person with AB cannot donate to a person with O because the receiver has antibodies(alpha and beta) that bind to the antigens on the AB blood cells, causing death.

Which combination of characteristics in a population would provide the greatest potential for evolutionary change?
labwork [276]

Which combination of characteristics in a population would provide the greatest potential for evolutionary change?

a. large population, few mutations

b. small population, many mutations

c. small population, few mutations

Small population, many mutations are the combination of characteristics in a population would provide the greatest potential for evolutionary change.

b. small population, many mutations

<u>Explanation:</u>

Stabilizing selection in development is a kind of common choice that supports the normal people in a populace. In little, reproductively detached populaces, extraordinary conditions exist that can create fast changes in quality frequencies absolutely autonomous of transformation and normal determination.

Natural Selection prompts a transformation change when a few people with specific qualities in a populace have higher endurance and regenerative rate than others and give these inheritable hereditary highlights to their posterity. The power of Natural Selection aside, populace size is as yet a factor to be considered.

Sati [7]

Option (D) flagellated protist is correct.

The last common ancestor of all animals was probably a flagellated protist.

<h3>What is a Protist?</h3>
  • Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist.
  • The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.
  • Protozoa is another name for protists that resemble animals. Some are parasites as well.
  • The four phyla that make up the Protozoa are flagellates, ciliates, spore-forming protists, and protists that resemble amoebas.
  • Nuclear membranes surround the DNA of protists.
  • Most protists are motile, or able to move, and many of them inhabit aquatic settings.
  • Protists can reproduce sexually and/or asexually, and their life cycles are intricate.
  • Protists consume, absorb, or produce food through photosynthesis.
