;[malesHMZDom maleHMZDom]; three genotypes of males homozyg dominant, heterzy, homozyg recessive
;[malesHETZ maleHETZ]; AA, Aa, aa
;[malesHMZRec maleHMZRec]
   ; different types of turtles and should be put with plural followed by singular
;[femalesHMZDom femaleHMZDom]; 3 genotypes of females (AA, Aa, aa)

breed [people person] 
breed [mosquitos mosquito] ; mosquito vector              ; example. [wolves wolf]

breed [forest]
people-own [ allele1 allele2 gender generation ] ; allows people and person to own attributes of genotype and gender
