Para establecer la relación entre antígenos y anticuerpos podemos tomar como ejemplo los grupos sanguíneos. Contesta Falso o Ver

dadero y justifica las falsas.
1-Los sistemas ABO y Rh están determinados genéticamente y se basan en respuesta asntígeno-anticuerpo.


2- En el sistema ABO la presencia o ausencia de los antígenos A y B en la superficie de los glóbulos rojos determina el grupo sanguíneo.


3- Los individuos cuyos glóbulos rojos poseen antígenos Rh se clasifican como Rh positivos mientras que los que carecen de antígenos Rh se clasifican como negativos.


4- La eritroblastosis fetal puede producirse cuando una madre Rh negativo está embarazada con un feto Rh positivo.

alekssr [168]

Answer: Hello your question is incomplete below is the complete question

Let’s look at a different gene locus, we’ll call it B. The normal, wild type, the population was 100% BB. There are 150 Pakicetus in the population at present. Assume Charles had another mutation; this one at the B locus, to produce allele b. What is the gene frequency of allele b in the population if the population of Pakicetus reaches 100,000

answer : ≈ 1

Explanation:

<u>Determine the Gene frequency of allele b </u>

Population = 100,000

There are 150 Pakicetus in population i.e. 300 alleles at locus B

hence the frequency of b = 1/300 = 0.33%

Increase in population does not affect frequency of b ( HW equilibrium )

<em>therefore the Gene frequency of allele b </em>

= 0.33% * 0.33% * 100000 = 1.08  

≈ 1
