Document Summary

Describe the basic process of conception to the point of forming the zygote. Explain the basic concepts of hereditary and their relationship to each other: cells, chromosomes, genes, dna, alleles. Describe passive, evocative, and active gene correlations, including the relative development influence over time and age. The zygote and the production of body cells. Due to crossing over, there are 8 million possible gamete chromosome combinations per gamete. A gene is differentially expressed depending on environmental factors. A gene may confer a risk or predisposition, but its expression depends on other factors. Ex) aggression predisposition hinges on early attachment and care (primates) Multiple forms of a gene on two strands of dna. One gene (location on a chromosome) with different versions of the gene. Recessive genes are in the minority, and many recessive genes are maladaptive. Genetics: a vulnerability was inherited from the mother. Parent genotype can influence the environment that the parents provide to their children.
