D)coaction of genetic and chromosomal abnormalities.

Question

Quizplus · Accepted Answer

Teratogens, such as drugs or environmental toxins, can have damaging effects on fetal development by interacting with the genes of the developing baby. This interaction between genes and environment is referred to as coaction, and it is the reason why some fetuses may be more susceptible to the harmful effects of teratogens than others. While genetic mutations or chromosomal abnormalities can also have damaging effects on fetal development, these are not necessarily the result of teratogen exposure. Similarly, dominant, defective alleles would only be relevant in cases where there is a genetic predisposition to a particular disorder or condition.
