The carbon atoms gradually transform into another type of carbon atom. they can tell the age by the percentage of each type of carbon an artifact has.
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
Answer:
The correct answer is option E, that is, toxic epidermal necrolysis.
Explanation:
The painful exfoliation of the mucous membranes and the skin two weeks after starting allopurinol indicates Toxic Epidermal Syndrome. A potentially life-threatening dermatologic ailment featured by widespread necrosis, erythema, and bullous detachment of the mucous membranes and epidermis is known as the toxic epidermal necrolysis. The further leads to exfoliation, and possible death or sepsis.
