Document Summary
Children who are breastfed have higher iq than those who are not. Fatty acids in breastmilk are important in brain development; fads2 is involved in fatty acid metabolism. Study showed that being breastfed was only an advantage (in terms of being smarter), if you had a c" allele of this gene (either homozygous or heterozygous) Results are reflected in the graph- being able to metabolise fatty acids made a significant difference when breastfed, as opposed to not being able to. Nature and nurture- stages of prenatal development, and understanding how genetic sequences of development are influenced by environmental factors (using examples of teratogens- agents or factors which cause malformation of an embryo) Formation of major organs: foetal period, from 9th week until birth (38 weeks, organ systems begin to function, organism grows. Note*: the egg, once fertilised in the fallopian tubes, begins to divide repeatedly as it moves down to the uterus.
