Onenote online (cid:1006)/6/(cid:1005)8: evolution (cid:271)y natural sele(cid:272)tion, mutation. Tuesday, february 6, (cid:401)(cid:399)(cid:400)8 9:(cid:401)(cid:403) am: good of the individual, not the species. Nothing about individual selection process that will guarantee a species wont go extinct. Evolution is increasing the frequency of variance: two types of selection to describe which individuals are going to do well: Hard selection: hard criteria , relative to threshold, ex: cold tolerance , (cid:401)(cid:399) to 8(cid:399) degrees for everyone (cid:336)ideal(cid:337, drop temp falls below (cid:401)(cid:399) some individual"s can survive; others don"t, can cause extinction. P= = (cid:399). (cid:404)a + (cid:399). (cid:404)b(cid:399) = generation of (cid:400) Generation(cid:401): = . (cid:403)(cid:404)a + . (cid:403)b: if you loose an alleles but one , that allele is fixed, fixation when it goes to (cid:400)(cid:399)(cid:399), inheritance. Single locus particulate, blended: particulate = pure dominance, blended= anything incomplete dominance. Two categories: (cid:402) bigs, one little (cid:336)aabb(cid:337, (cid:402) littles, on big (cid:336)aabb(cid:337, (cid:404)(cid:399)/(cid:404)(cid:399) (cid:336)aabb(cid:337)
