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
The answer is illogical conclusion. Logic is the science that investigates the principles governing correct or reliable inference. Any conclusion based on scientific investigation and relying from fact on the ground has the potential of being accepted as true and sound, unlike illogical conclusions, where inferences are made without a support of a data.
Autotrophes
They make their food through photosynthesis.
Hope this helps.
Answer:
Nine
Explanation:
These are called carrier proteins, and they have what it is called: solute-binding sites, that when saturated, they are considered "full".
Each different amino acid needs a separate carrier protein to move it across the plasma membrane, so that's 3, then the four different sugars need separate carriers as well, we add 4 more then, we have 7 so far, finally the 2 different ions use 2 more, plus the other 7, totals 9.
