What was Oklahoma's role in the Spanish and French exploration of North America in the 1600s and 1700s? (Site 1)
Answer:
yes because the animal changed over time
Explanation:
The possible genotype would be when one of the parent is homozygous dominant - Phenotype ratio= 16:0, genotype ratio= 1 YYRR : 1YYRr: 1 yYRR: 1 YyRr.
when one of the parent is homozygous recessive the phenotype ratio is 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle and genotype ratio = YyRr: Yyrr: yyRr: yyrr or
1:1:1:1 genotype ratio.
Explanation:
The data given:
yellow and round dominant --- Y R
Green and wrinkle recessive ---- yr
It is given a true breeding plant, which means the parent plant is homozygous for the trait. Let one of the parent be YYRR
Also it is given that it was crossed with heterozygous parent so the other parent be YyRr
The cross between them is shown in punnet square as:
YR Yr yR yr
YR YYRR YYRr yYRR YyRr
YR YYRR YYRr YyRR YyRr
YR YYRR YYRr YyRR YyRr
YR YYRR YYRr YyRR YyRr
4 YYRR: 4 YYRr: 4 YyRR: 4 YyRr
thus genotype ratio is 1:1:1:1
phenotype ratio all 16 are yellow and round.
In case when either parent is homozygous recessive is crossed with heterozygous parent. The punnet square for this is shown as:
yyrr X YyRr
YR Yr yR yr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
4 YyRr: 4 Yyrr: 4yyRr: 4yyrr
1:1:1:1 genotype ratio
phenotype ratio = 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle.
Thus phenotype ratio is 1:1:1:1
In electron transport chain, the multiprotein structure pumps out H+ ions into the intermembrane space. As the H+ ions get pumped out, the concentration of H+ in the intermembrane space gets higher. As a result, H+ ions will start flowing down back to the chromosomes matrix through the ATP molecule.
