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 fMRI is now the most commonly used method of learning about brain structure.
Functional magnetic resonance imaging (fMRI) is a type of brain scan that uses a magnetic field to create images of brain activity in each brain area.
The fMRI detects the amount of blood flow in each brain region, and thus is an indicator of neural activity. Very clear and detailed pictures of brain structures can be produced via fMRI.
The advantage of the fMRI is that it is noninvasive, fMRIs are substantial and they are now available in many university and hospital settings. The fMRI is now the most commonly used method of learning about brain structure.
Our words are bound by an invisible grammar which is embedded in the brain.

Eukaryotic chromosomes contain both DNA and protein tightly packed together to form Chromatin.
Velocity is how fast the river is moving, the Volume is how much is in the river!
The correct answer is A. The phenotype of the F1 generation exhibit all inflated pods since allele P which characterizes inflated pods is the dominant trait. They only carry the allele p which characterizes constricted pods but they will not exhibit the trait. This recessive trait is masked by the presence of the dominant trait.
