Question

multiple choice question fetuses that show fewer negative effects of maternal smoking are believed to be protected by their—— o pancreas o genotype o blood type o x chromosomes

Explanation:

Genetic factors, specifically an individual's genotype, can influence how a fetus responds to environmental stressors like maternal smoking. Variations in genes can lead to differential susceptibility, with certain genotypes conferring protection against the negative impacts of smoking exposure in utero. The other options (pancreas, blood type, X chromosomes) do not have established links to this specific protective effect.

Answer:

O genotype
