The probable genotype of the IV-3 with the perspective of autosomal inheritance will be A because he does not have condition A. Therefore both parents must be in condition A.
The probable genotype of IV-3 with the perspective of set=linked inheritance will be BbY this is because he has B condition. Therefore the mothers' genotype must be XBXb and the father's genotype must be XBY.
The probability of IV-4 having condition A is 1/36
I believe the correct answer is option C. Weathering produces the sediments that ultimately lead to soil formation. Soil formation is the result of a combination of five factors: parent material, climate, topography, biological factors, and time. Hope this answers the question.

Gonads are the reproductive organs that produce gametes.
Gametes are also known as sex cells. They are produced by the gonads. In males, the gonads are the testes. The gametes that are produced by males are called sperm cells. In females, the gonads are the ovaries. The gametes that are produced by females are called egg cells.
