How/why did sickle cell anemia increase in frequency in the human population?

Levart [38]

Answer:

The character of sickle cell anaemia does not get fixed in the population Because it has more disadvantages than advantages

Explanation:

Any character will get fixed in the population if the character provides the progeny certain advantage to reproduce better.The rate of malaria infection is low, but such people may have breathing difficulties and organs may fail due to the wrinkled RBC's not able to flow smoothly in the arteries and hence causing blockages. the character may be recessive but again the amount of oxygen carried per healthy RBC is less and that makes breathing difficult . so as a character its a disadvantage for the person who is a career and hence not being selected to be fixed.

A couple without an ancestral history of Tay-Sachs disease (a rare autosomal recessive) have two normal children and an infant a

Bas_tet [7]

Answer:

The probability is 25%.

Explanation:

Let the dominant allele for the disease be 'T' and recessive allele be 't'.

The couple with normal phenotype produces an infant with the Tay Sach's disease.
As the disease is autosomal recessive in nature, it will get expressed in a homozygous recessive condition, that is, when the genotype is : tt.
As the normal parents are producing a diseased offspring, the both parents must be heterozygous dominant (Tt) for the disease allele.
The brother of the husband and the sister of the wife, both having a normal phenotype, can have the following genotypes, TT or Tt.
If either of the individual (brother or sister) has TT genotype and the other has other has either TT or Tt genotype, there is zero probability that they will produce an offspring with the disease.

T T and T T

T TT TT T TT TT

(N) (N) (N) (N)

T TT TT t Tt Tt

If both the individuals have a Tt genotype, the probability to produce diseased offspring is one-fourth or 25%.
