Answer: Fever is a common symptom of illness. The Centers for Disease Control and Prevention (CDC) defines fever as a temperature above 100.4° F, though children often run higher fevers than adults.
Many types of infection can cause fever, as your body will increase temperature to effectively fight off the virus or bacteria causing the infection. These fevers will usually resolve themselves as your body works to get rid of the foreign invader.

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.
Answer:
Option A, 1/64
Explanation:
The genotype of a carrier female would be Pp
The genotype of a carrier male would be Pp
When these two adults are crossed , the following offspring are produced
Pp x Pp
PP, Pp, Pp, pp
Thus out of four children 3 children have normal phenotype but two are carrier.
So probability of having one normal child (with genotype PP) is 
So the probability of three normal children is

Hence, option A is correct
It is incorrect its B.tropism
