Aggressive behaviors by the dominant individual influence the hormone concentrations in subordinate individuals, maintaining them as immatures or in the other sex. Lygaeus another bug - two sex chromosomes: We got a bit off track here - deer have chromosomally determined sex determination; appreciate that this was just an example of selective abortion.

Relative size in a social setting has direct effects on sex determination in the Midas cichlid a fish. The resulting patterns of change are easy to see and can be followed through ensuing generations for more than million years -- major evolutionary timescales.
Because this trait is autosomal, it is governed by genes on a pair of homologous chromosomes that are NOT the sex chromsomes. Retroposons are repetitive DNA fragments that are sprinkled throughout the genome.
How can we understand this? In some societies, the expected 'social norm' of sexual preference for someone playing the gender role of a man is to be attracted to women.
Likewise, if a sperm with the mutant Y is used, then a zygote is produced that is XY but has no sry gene and developes into a female.

Sex Determination. In many organisms sex is determined genetically. Often this is accompanied by chromosomal differences between the sexes. Chromosomes.
Sex determination Most body cells contain chromosomes in matched pairs. European red deer Cervus elaphus have been shown to selectively abort male embryos in years where resources are in short supply. They are copied "reverse transcribed" from an RNA intermediary that randomly "jumps" to another locus within the genome where they insert themselves.
In progynous wrasses, one female in a school developes into a reproductive male who mates with the mature females. An Example of Sex-Linkage:
|In ancient Greece, sexual behavior was not as strongly correlated with our gender categories of 'man' and 'woman', but by the categories of the 'active role' adult, penetrative, maculine, higher social status and 'passive role' youth, feminine, lower social status.
We use the Z W symbols to represent sexes in these species. Well, it is understandable in light of natural selection and differential reproductive success in this harem-forming species.
Griffin and Jennifer A. The nature of these changes is poorly understood, but in both cases the social dynamics in the school have an effect. But the difference was demonstrated by identifying the sexes of mutants that lack or gain an extra sex chromosome.

Two of these are caused by alleles on the X chromosome. One of these pairs controls the inheritance of gender - whether offspring are male or female, in males, the two sex chromosomes are different.
What gave us new patterns was the way a genotype was expressed as a phenotype. Relative size in a social setting has direct effects on sex determination in the Midas cichlid a fish. Chromosomes from a male.
