Document Summary
Genetics: genetics is the study of the variation between and among living things, and how this variation is inherited (how variation arises) Genotype: describes the genetic constitution of an organism (what was inherited). Comes from a parent if haploid or parents if diploid. Phenotype: describes the morphological, biochemical (e. g. amylase production, hormone production) and behavioural (e. g. talkative, shy) properties of an organism resulting from a specific genotype and its interaction with the environment. * genome is the total amount of genetic material in a chromosome set (in humans one set of chromosomes) * sequencing a genome is working out the base sequence (adenine, thymine, cytosine and guanine) of the dna. * it does not tell the function of the sequence. * humans have 2 genomes nuclear genome and mitochondrial genome. * ge(cid:374)o(cid:373)es do(cid:374)"t (cid:373)atch the co(cid:373)ple(cid:454)it(cid:455) of a species, for i(cid:374)sta(cid:374)ce a (cid:449)or(cid:373) has (cid:374)earl(cid:455) the same number of genes as a human.
