Please help!!!! very confused pt 2
Schach [20]

Answer:

If the genotype of the parents are <em>Iᵃi </em>and <em>I</em>ᵇ<em>i, </em>then four type of offspring will be produced.The genotype of the offspring are, <em>IᵃIᵇ, Iᵃi,Iᵇi, </em>and <em>ii.</em>

Explanation:

<em>IᵃIᵇ = </em>As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

<em>Iᵃi= </em>In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

<em>Iᵇi= </em>In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

<em>ii= </em>This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.

arsen [322]

Answer:

The correct answer is C. In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Explanation:

The plaque assay is an approach used for titering bacteriophage stocks or determining the quantity of infectious virus in a sample. Plaques are visualized if you spot the phage on a lawn of growing compatible bacteria. Each plaque indicates an initial infection with one phage followed by lysis of neighboring bacteria in the lawn. Only viruses that cause visible damage of cells can be assayed in this way. The plaque assay is used to determine viral titer as plaque-forming units per ml so that known amounts of virus can be used to infect cells during subsequent work.

In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Evolution is the change in heritable traits of biological populations over successive generations.

What is evolution of life?

  • Evolution has produced the variety of life that exists on Earth today. Since life first emerged on Earth between 3.5 and 4 billion years ago, it has continued to develop.
  • At initially, there were just single-celled, primitive species on Earth.
  • The first multicellular organisms appeared much later, and as a result, the diversity of life on Earth significantly increased.
  • Darwin put out a substantial amount of evidence to back up his idea of evolution by natural selection.
  • Evolution is the gradual alteration of a living thing's traits over time. Natural selection is the process of evolution.
  • Through their DNA, organisms transmit their traits from one generation to the next.
