- Which of the following is NOT true while comparing internal to external fertilization. In external fertilization, zygotic DNA replication starts after the fusion of gamete pronuclei; in internal fertilization, the first zygotic DNA synthesis happens before pronuclei fusion. B Capacitation is only observed in internal fertilization. In both internal and external fertilization, the cortical granule reaction is required for the slow block to polyspermy. In external fertilization, intracellular calcium release is stimulated prior to gametes fusion; in internal fertilization, it happens after gametes fusion. In both internal and external fertilization, there is a slow and a fast block to polyspermy.arrow_forward..arrow_forwardChromosomes Genetic mutation Syndrome Internal reproductive anatomy External genitalia Secondary sex characteristics Sex typically assigned at birth Barr body (Y/N) SRY gene (Y/N) Testosterone (Low/High) Menstruation (Y/N) Fertile (Y/N) 46,XX None None Female Female Female Female YES NO Low YES YES 46,XX CYP21A2 mutation or deletion Congenital adrenal hyperplasia Female Ambiguous Male but reduced Female 46,XY SRY mutation or deletion Swyer syndrome Female but nonfunctional ovaries Female Absent or female, but reduced Female 45,X Complete or partial loss of X chromosome Turner syndrome Female but absent or nonfunctional ovaries Female Absent or female, but reduced Female 46,XY Androgen receptor (AR) deletion Complete androgen insensitivity syndrome…arrow_forward
