Ciltskoka analīze Matu krāsa

Ciltskoka analīze Matu krāsa. Alma Eihentāle ae11032. Recesīvā pazīme – gaiša matu krāsa. Matu krāsu nosaka eimelanīna un feomelanīna daudzums. Gaišo matu frekvence šajā ciltskokā – 37%. AA 1/3 p 2 /(p 2 +2pq)=0,25/(0,25+2*0,5*0,5)=0,(3)=1/3 Aa 2/3

  1. Ciltskoka analīzeMatu krāsa Alma Eihentāle ae11032

  2. Recesīvā pazīme – gaiša matu krāsa • Matu krāsu nosaka eimelanīna un feomelanīna daudzums

  3. Gaišo matu frekvence šajā ciltskokā – 37%

  4. AA 1/3 p2/(p2+2pq)=0,25/(0,25+2*0,5*0,5)=0,(3)=1/3 Aa 2/3 2pq/(p2+2pq)=2*0,5*0,5/(0,25+2*0,5*0,5)=0,(6)=2/3 Ja a=0,37  A=1-0,37=0,63 AA p2/(p2+2pq)=0,372/(0,372+2*0,37*0,63)≈ 0,23 Aa 2pq/(p2+2pq)=(2*0,37*0,63)/(0,372+2*0,37*0,63)≈0,77 0,77+0,23=1

  5. Ja māte ir Aa, tad varbūtība, ka meita ir Aa, ir 2/3, bet AA 1/3 Ja māte ir AA, tad varbūtība, ka meita ir Aa un AA, ir 0,5 katram variantam

  6. Ja IV paaudzē mana tēva vecāki ir: • Aa x Aa, tad katram bērnam 2/3, ka Aa, un 1/3, ka AA • AA x Aa, tad katram bērnam ½, ka Aa, un ½, ka AA • AA x AA, tad visi (1) bērni ir AA
