Answer:
20 percent
Explanation:
There are some conditions and agents which can impair prenatal development and lead to birth defects or even death knows as teratogens. For example, viruses, drugs, stressors, and malnutrition. Teratogens that can harm the prenatal brain, affecting the future child's intellectual and emotional functioning know as Behavioral teratogens. These increase the risk of harm to developing children. Some can influence the effect of teratogens.
1. Timing--- at which phase of pregnancy, developing organism exposed to the teratogen, either in 1st, 2nd or 3rd trimester.
2. Exposure-- at what dose or frequency of exposure of the teratogen, newborn is going to expose.
3. Genetic variability-- genetic makeup of newborn makes her more susceptible to the effect of a teratogen.
According to literature, 20 percent of behavioral teratogen can affect the newborn.

Answer:
Duplication of the Dax1 is associated to equivocal sex determination on how XY mice develop ovaries and a female phenotype which comes from strong expression of the homologous gene (Ahch) in the first stages of gonadal (and adrenal) differentiation.
Explanation:
Dose-Sensitive Sex Reversal Locus on Chromosome X, Gene 1
, DAX1∗ (officially, nuclear receptor subfamily 0, group B, member 1; NR0B1) is a member of the nuclear hormone receptor superfamily of transcription factors that functions primarily as a transcriptional repressor.
Duplication of the DAX1/NROB1 locus is associated with male-to-female sex reversal, that is ambiguous external genital differentiation ranges.
One X chromosome and one Y chromosome in each diploid cell of their bodies differencite males from females, who typically have two X chromosomes but XX males that are SRY-positive have two X chromosomes, with one of them containing genetic material from the Y chromosome, making them phenotypically male but genetically female.
DAX1 protein may be directly or indirectly involved in gonadal regulation of hypothalamic-pituitary function.
