Answer: True.
Spleen framework is created by reticular fibres from reticular cells.
Explanation:
Spleen is an organ found mostly in vertebrates. It develop from mesenchymal cells within the dorsal of mesogastrium near the greater curvature stomach. The mesencymal cells then divide and differentied to form framework of connective tissues of spleen. The framework of spleen is created by reticular fibres of the reticular cells. Reticular fibres are fibres in the connective tissue that is composed of type iii collagen secreted by reticular cells. Spleen function in filtering of blood. It plays a major role in red blood cells and immune system.
Answer:
50% or 1/2. The result remains unchanged if the husband were to have G6PD.
Explanation:
For X-linked recessive inheritance, a female (XX) needs two recessive alleles to be affected while a male needs only one (XY). It is hypothetically assumed that the Y chromosome does not carry any trait.
Assuming the allele for the disease is represented by g, a woman whose father suffered from G6PD is a carrier for the disease with genotype
. A normal man will have the genotype
. When the 2 marries:
x
=
It thus means that 50% or 1/2 of their sons will be expected to have G6PD.
Now, assuming the husband has G6PD, the mating becomes:
x
=
50% or 1/2 of their sons is still expected to have G6PD. The ratio remains unchanged.
