... • Sex cells (sperm or egg) contain only 23 chromosomes. Every egg has an X, half of sperm have X, half Y. The Y chromosome has the instructions to make a male. • At fertilisation, if a Y sperm fertilises an egg, a male will develop. If an X sperm fertilises an egg a female will develop. ...

Regulation of Gene Expression

Gene-Environment and Gene
... • Genes and environment work together • Genes also influence other genes (epistasis) • Therefore: • Not everyone is equally susceptible to stressors, toxins, etc. • This is the way it really works – I did not say that life is fair! ...
