A normal man and a normal woman both having one of their parent albino, if get married then what is the probability of their child of being albino?
1 \(20 \%\)
2 \(25 \%\)
3 \(75 \%\)
4 \(80 \%\) JPMER-2019
Explanation:
: A normal man and a nomal women both having one of their parent albiro, if get mamied then \(25 \%\) is the probability of their child of being albino. - The term albinism refers to oculocutaneous albinism-a group of inherited cisorder where there is little or no production of the rigment melanin.

In a person suffering from sickle cell anaemia, the \(\qquad\) becomes half moon shaped.
1 RBC
2 Thrombocyte
3 Monocyte
4 Lymphocyte
Explanation:
: People who have sickle cell anaemia inherit two genes, one from each parent, that code for hemoglobin " S ". Haemoglobin \(S\) is an abrormal form of haemoglobin that causes the red cells to become rigid and sickle shaped. This is commonly called sickle cell anaemia and is usually the most severe form of the clisease.

One of the following is NOT an example of incomplete sex-linkage.
1 Total colour-blindness
2 Retinitis pigmentosa
3 Nephritis
4 Myopia
Explanation:
It is also known as night blindness. This disease is inherited in an X-Linked recessive pattern. Hence one copy of an affected gene on the X chromosome in males is sufficient to result in myopia, whereas females with both affected genes have the disease. In complete linkage produces new combinations of the genes in the progeny due to the formation of chiasma and the occurence of crossing over in between the linked genes are present on homologous chromosomes. The incomplete linkage is seen in the genes that are present on the homologous part of sex chromosomes, and it is also seen in pea plants.

How many Barr bodies are present in the cells of Klinfelter Male (KM), Normal Male (M) and Normal Female (F) in humans
: Sex chromatin is named as Barr body. Barr body can easily be demonstrated in the cell of buccal eqithelium and hair roots. Barr body is a highly condensed structure lies against the nuclear mermbrane of inter-phase cells of females. Human female is sex chromatin positive and male is sex chromatin negative, the number of Barr bodies is one less than the number of X-chromosome. Therefore, 1 barr body is present in Klinefelter male (KM), there is no barr body in normal male (M), one barr body is present in tormal female (F) in humans.
