第五章多基因病第一节多基因遗传与数量遗传数量性状与多基因假说质量性状(qualitativecharacter)单基因遗传中所涉及的遗传性状都是由对基因所控制,相对性状之间的差别明显,一个群体中的变异分布是不连续的,可将变异的个体明显地区分为2~3组,没有中间类型,这类性状称为质量性状。第五章多基因病1图1AA和Aaaa图2aaAaAA图1AA和Aa2数量性状(quantitativecharacter)与上述的性状不同,多基因遗传性状在个群体中变异的分布是连续的,呈正态分布,即大部分个体属于中间类型,极端变异的个体极少,而且个体之间只有量的差别而没有质的差别。即性状变异在群体中的分布是连续的,不同个体间的差异只是量的差异,变异很小,称为数量性状(quantitativecharacter)数量性状(quantitativecharacter)3医学遗传学多基因病课件4变员数0m004130140150160170180190200身高cm变员数5医学遗传学多基因病课件6医学遗传学多基因病课件7医学遗传学多基因病课件8医学遗传学多基因病课件9医学遗传学多基因病课件10医学遗传学多基因病课件11医学遗传学多基因病课件12医学遗传学多基因病课件13医学遗传学多基因病课件14医学遗传学多基因病课件15医学遗传学多基因病课件16医学遗传学多基因病课件17医学遗传学多基因病课件18医学遗传学多基因病课件19医学遗传学多基因病课件20医学遗传学多基因病课件21医学遗传学多基因病课件22医学遗传学多基因病课件23医学遗传学多基因病课件24医学遗传学多基因病课件25医学遗传学多基因病课件26医学遗传学多基因病课件27医学遗传学多基因病课件28医学遗传学多基因病课件29医学遗传学多基因病课件30医学遗传学多基因病课件31医学遗传学多基因病课件32医学遗传学多基因病课件33医学遗传学多基因病课件34医学遗传学多基因病课件35医学遗传学多基因病课件36医学遗传学多基因病课件37医学遗传学多基因病课件38医学遗传学多基因病课件39医学遗传学多基因病课件40医学遗传学多基因病课件41医学遗传学多基因病课件42医学遗传学多基因病课件43医学遗传学多基因病课件44医学遗传学多基因病课件45医学遗传学多基因病课件46医学遗传学多基因病课件47医学遗传学多基因病课件48医学遗传学多基因病课件49医学遗传学多基因病课件50医学遗传学多基因病课件51医学遗传学多基因病课件52医学遗传学多基因病课件53医学遗传学多基因病课件54医学遗传学多基因病课件55医学遗传学多基因病课件56医学遗传学多基因病课件57医学遗传学多基因病课件58医学遗传学多基因病课件59医学遗传学多基因病课件60医学遗传学多基因病课件61医学遗传学多基因病课件62医学遗传学多基因病课件63医学遗传学多基因病课件64医学遗传学多基因病课件65医学遗传学多基因病课件66医学遗传学多基因病课件67医学遗传学多基因病课件68医学遗传学多基因病课件69医学遗传学多基因病课件70医学遗传学多基因病课件71医学遗传学多基因病课件72医学遗传学多基因病课件73医学遗传学多基因病课件74医学遗传学多基因病课件75医学遗传学多基因病课件76医学遗传学多基因病课件77医学遗传学多基因病课件78医学遗传学多基因病课件79医学遗传学多基因病课件80医学遗传学多基因病课件81医学遗传学多基因病课件82医学遗传学多基因病课件83医学遗传学多基因病课件84医学遗传学多基因病课件85医学遗传学多基因病课件86医学遗传学多基因病课件87医学遗传学多基因病课件88医学遗传学多基因病课件89医学遗传学多基因病课件90医学遗传学多基因病课件91医学遗传学多基因病课件92医学遗传学多基因病课件93医学遗传学多基因病课件94医学遗传学多基因病课件95医学遗传学多基因病课件96医学遗传学多基因病课件97医学遗传学多基因病课件98医学遗传学多基因病课件99医学遗传学多基因病课件100医学遗传学多基因病课件101医学遗传学多基因病课件102医学遗传学多基因病课件103医学遗传学多基因病课件104医学遗传学多基因病课件105医学遗传学多基因病课件106医学遗传学多基因病课件107医学遗传学多基因病课件108医学遗传学多基因病课件109医学遗传学多基因病课件110医学遗传学多基因病课件111医学遗传学多基因病课件112医学遗传学多基因病课件113医学遗传学多基因病课件114医学遗传学多基因病课件115医学遗传学多基因病课件116医学遗传学多基因病课件117医学遗传学多基因病课件118医学遗传学多基因病课件119医学遗传学多基因病课件120医学遗传学多基因病课件121第五章多基因病第一节多基因遗传与数量遗传数量性状与多基因假说质量性状(qualitativecharacter)单基因遗传中所涉及的遗传性状都是由对基因所控制,相对性状之间的差别明显,一个群体中的变异分布是不连续的,可将变异的个体明显地区分为2~3组,没有中间类型,这类性状称为质量性状。第五章多基因病122图1AA和Aaaa图2aaAaAA图1AA和Aa123数量性状(quantitativecharacter)与上述的性状不同,多基因遗传性状在个群体中变异的分布是连续的,呈正态分布,即大部分个体属于中间类型,极端变异的个体极少,而且个体之间只有量的差别而没有质的差别。即性状变异在群体中的分布是连续的,不同个体间的差异只是量的差异,变异很小,称为数量性状(quantitativecharacter)数量性状(quantitativecharacter)124医学遗传学多基因病课件125变员数0m004130140150160170180190200身高cm变员数126医学遗传学多基因病课件127医学遗传学多基因病课件128医学遗传学多基因病课件129医学遗传学多基因病课件130医学遗传学多基因病课件131医学遗传学多基因病课件132医学遗传学多基因病课件133医学遗传学多基因病课件134医学遗传学多基因病课件135医学遗传学多基因病课件136医学遗传学多基因病课件137医学遗传学多基因病课件138医学遗传学多基因病课件139医学遗传学多基因病课件140医学遗传学多基因病课件141医学遗传学多基因病课件142医学遗传学多基因病课件143医学遗传学多基因病课件144医学遗传学多基因病课件145医学遗传学多基因病课件146医学遗传学多基因病课件147医学遗传学多基因病课件148医学遗传学多基因病课件149医学遗传学多基因病课件150医学遗传学多基因病课件151医学遗传学多基因病课件152医学遗传学多基因病课件153医学遗传学多基因病课件154医学遗传学多基因病课件155医学遗传学多基因病课件156医学遗传学多基因病课件157医学遗传学多基因病课件158医学遗传学多基因病课件159医学遗传学多基因病课件160医学遗传学多基因病课件161医学遗传学多基因病课件162医学遗传学多基因病课件163医学遗传学多基因病课件164医学遗传学多基因病课件165医学遗传学多基因病课件166医学遗传学多基因病课件167医学遗传学多基因病课件168医学遗传学多基因病课件169医学遗传学多基因病课件170医学遗传学多基因病课件171医学遗传学多基因病课件172医学遗传学多基因病课件173医学遗传学多基因病课件174医学遗传学多基因病课件175医学遗传学多基因病课件176医学遗传学多基因病课件177医学遗传学多基因病课件178医学遗传学多基因病课件179医学遗传学多基因病课件180医学遗传学多基因病课件181医学遗传学多基因病课件182医学遗传学多基因病课件183医学遗传学多基因病课件184医学遗传学多基因病课件185医学遗传学多基因病课件186医学遗传学多基因病课件187医学遗传学多基因病课件188医学遗传学多基因病课件189医学遗传学多基因病课件190医学遗传学多基因病课件191医学遗传学多基因病课件192医学遗传学多基因病课件193医学遗传学多基因病课件194医学遗传学多基因病课件195医学遗传学多基因病课件196医学遗传学多基因病课件197医学遗传学多基因病课件198医学遗传学多基因病课件199医学遗传学多基因病课件200医学遗传学多基因病课件201医学遗传学多基因病课件202医学遗传学多基因病课件203医学遗传学多基因病课件204医学遗传学多基因病课件205医学遗传学多基因病课件206医学遗传学多基因病课件207医学遗传学多基因病课件208医学遗传学多基因病课件209医学遗传学多基因病课件210医学遗传学多基因病课件211医学遗传学多基因病课件212医学遗传学多基因病课件213医学遗传学多基因病课件214医学遗传学多基因病课件215医学遗传学多基因病课件216医学遗传学多基因病课件217医学遗传学多基因病课件218医学遗传学多基因病课件219医学遗传学多基因病课件220医学遗传学多基因病课件221医学遗传学多基因病课件222医学遗传学多基因病课件223医学遗传学多基因病课件224医学遗传学多基因病课件225医学遗传学多基因病课件226医学遗传学多基因病课件227医学遗传学多基因病课件
