A type O woman marries a man with type B blood, given that both of their mothers were type O, predict their possible offspring.

For a woman with type O blood and a man with type B blood, whose mother was of type O blood, the possible offspring will consist of B and O children.

Explanation:

Blood type is an inherited trait and is determined by the presence or absence of antigens A and B on the surface of the erythrocyte:

In the above case, the woman has an O blood type, whose genotype is O|O. The male must be heterozygous, since his mother was of blood type O, so his genotype is B|O.

To know the possible descendants of this couple, the crossing of the wolf alleles must be done:

Alleles      B      O

O              B|O   O|O

O              B|O   O|O

From where the probabilities of the offspring are obtained:

Therefore, from this crossing only descendants of individuals with blood type B and O can be obtained.

is called echinoderms

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
