Answer:
1. Klinefelter syndrome
2. Nobody can be born with a single X chromosome
Explanation:
1. A genetic condition in which a male is born with an extra copy of the X chromosome
Klinefelter's syndrome isn't inherited, but rather occurs only as a result of a random genetic error after conception.
Males born with Klinefelter's syndrome may have low testosterone and reduced muscle mass, facial hair and body hair. Most males with this condition produce little or no sperm,
2. Sex chromosome occurs due to combination of the X and Y chromosome of both parents.
Answer:
15.21 %
Explanation:
If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:
p + q = 1
p² + 2pq + q² = 1
where;
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
Given that p= 0.68 and q = 0.39
the percentage of the homozygous recessive genotype (q² ) will be
(0.39)² = 0.1521
= 0.1521 × 100
= 15.21 %
∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %
Inherited genetic factors : hope it helps
Answer:
Fluorescence-Activated Cell Sorting or FACS is a method that allows us to sort out different cell types on the basis of fluorescence emitted by cell membrane components bound compounds.
In the case of CD95 integral protein which is known for highly glycosylated, if use antibodies against cells with CD95 marker, will not identify glycans and can’t be targeted by antibodies as antibodies only recognize protein structures.
Therefore, two different proteins should be used in order to get the correct sorting of cells. One of these would bind to these glycosylations, and the other would be antibodies (with a fluorescent tag) against first.
