[C] (i), (iii) and (iv) A₂B is a compound made up of two elements A and B in a fixed ratio. The properties of a compound (e.g., A₂B) are entirely different from those of its constituent elements (e.g., A and B). The composition of a compound is fixed.

When a progeny of F1 is crossed with the homozygous recessive parent, it is called test cross. Such a cross is useful to determine the genotype of an unknown i.e., whether it is heterozygous, or homozygous dominant for the trait.

If the testes fail to descend to the scrotum, gametogenesis could be inhibited, the process of spermatogenesis require a marginally lesser ambient temperature than that in the abdominal cavity.

Reproductive health refers only to healthy reproductive functions. Comment.
Reproductive health refers to a total well-being in all aspects of reproduction i.e., physical, behavioural, psychological, social and physiological.

See lessDuring reproduction, the chromosome number (2n) reduces to half (n) in the gametes and again resume the original number (2n) in the offspring, what are the processes through which these events take place?
Halving of chromosomal number takes place during gametogenesis and regaining the 2n number occur as a result of fertilisation.
