Each ABO blood group is associated with the presence/absence of RBC antigens and the presence/absence of antibodies in the plasm
harina [27]

Answer:

a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma

b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma

c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma

d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma

Explanation:

ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.

The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.

Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.

Type A blood group has A antigen on RBC and has antibody B in the plasma.

Type B blood group has B antigen on RBC and has antibody A in the plasma.

Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.

Elephant seals are abundant in their population size but they have low genetic diversity within their species due to overhunting
Anastasy [175]
<h2>Genetic diversity </h2>

Explanation:

If the environment changes, the species runs the risk of not having the genetic diversity to be adaptable to that change and could go extinct

  • Genetic diversity is the diversity  or genetic variability within species
  • The huge variety of different gene sets defines an individual or a whole population's ability to tolerate stress from any given environmental factor
  • While some individuals might be able to tolerate an increased load of pollutants in their environment, others carrying different genes might suffer from infertility or even die under the exact same environmental conditions;the former will continue to live in the environment the latter will either have to leave it or die
  • Any change in the environment - natural or human induced causes a selection of events that only the fittest survive
  • In case of elephant seals,overhunting reduces the sum of genes available,thus leaving behind a population that is less capable of tolerating any further natural or human disturbances in environment
  • The loss of genetic diversity within a species can result in the loss of useful and desirable traits
