multiple choice question
which of the following is the term that describes the period of development of a fetus between conception and birth?

embryonic stage
reaction range

• Reaction range refers to the range of possible phenotypes for a genotype, unrelated to fetal development timing.
• Gestation is the full period of fetal development from conception until birth.
• The germinal stage is the first 2 weeks post-conception, only the initial phase of development.
