Why is it important to have a large gene pool? What are lethal alleles in the gene pool? Why do gene pools only apply to populations not species? What represents the alleles in a gene pool? What does deme mean in biology (genes/mating)?
What is the function of the SRY gene? What are chromosomes made of? Describe the developmental direction. In which direction does the primitive streak run? What do random mutations have to do with evolution? What would the absence of acetylcholinesterase at a synapse lead to?
“The only DNA differences between men and women are extremely small, limited to the single chromosome that is either X in the women or Y in the men,”(61). Within the male Y chromosome lies the SRY gene, or as Epstein likes to sexistly portray it as, “the athleticism gene,”(61)...
Importantly, the sexually dimorphic brain, similar to most sex differences, does not fall into a hard binary readout—but rather is on a continuum or spectrum with each cell and each brain region comprised of varying degrees of 'male' and 'female' (Hines, 2005; Joel and McCarthy, 2016)....

The scientists believe that this extra piece of DNA is like a switch that turns on SOX9, even without the SRY gene. To test their idea, they put this extra DNA into mice and found out that it made SOX9 work better. This means that even without SRY, SOX9 can still do its job, thank...
Male-to-female transsexuals were more likely to have a particular number of tandem repeats in the AR gene. As it turns out, Alaina does, indeed, have this variation. (We didn’t test the other woman’s full genome, so we don’t know if she does.) What this means for you A ...

Byanon121945— On Oct 26, 2010 The Drs who discovered the XXY karyotype was not Dr Harry Klinefelter, he is the Dr who had his name first on the paper that described Klinefelter's syndrome in 1942, Klinefelter et al. The persons who are responsible for discovering the XXY karyotype are ...
This would be fine if the measurement of the electron spin were always up and the measured spin of the positron were always down. But because of quantum mechanics, the spin of each particle is both part up and part down until it is measured. Only when the measurement occurs does t...
