Document Summary
Genetics is the study of genes, inheritance patterns, and genetic variation among organisms. Can affect diseases and mortality i. e. cancer progression can be related to genetic makeup. 5 different single nucleotide polymorphisms (changes); 5 different dna changes within different genes that can lead to aggressive prostate cancer. Ex ovo omnia (all from the egg: william harvey - 1651, epigenesis: substances present in egg differentiate into adult structures. Each sperm thought to contain a miniature adult: all structures were present and creature just got larger. Female was dirt for sperm to grow. Natural selection: based on observation that populations consist of more individuals than can be supported. Those w/ heritable traits that enhance survival persist. Experimented w/ pea plants in the monastery garden 1856 1863; published his studies in 1866. Walter sutton and theodor boveri (early 1900 s) Proposed that heritable features (genes) are carried on chromosomes. This means that 1 copy of each chromosome is received from each parent.
