1. perform a cross between two pea plants with the following characteristics: one is heterozygous for the dominant trait of wrinkled seeds (w); the other is homozygous for the recessive trait of smooth seeds (w). fill in the genotypes of the offspring in the punnett square. then state the percentages of each genotype and phenotype of the offspring.

Possible Genotypes are Ww and ww

Percentage of genotype Ww - %

Percentage of genotype ww - %

Possible phenotypes are Wrinkled and smooth

Percentage of Wrinkled  phenotype  - %

Percentage of smooth phenotype - %

Explanation:

Given -

Parent I  is heterozygous for the dominant trait of wrinkled seeds. Thus, its genotype would be "Ww"

Parent II is homozygous for the recessive trait of smooth seeds. Thus, its genotype would be "ww"

The punnet square representing the cross between "Ww" and "ww" is as follows -

Ww

wWwww

wWwww

Possible Genotypes are Ww and ww

Percentage of genotype Ww - %

Percentage of genotype ww - %

Possible phenotypes are Wrinkled and smooth

Percentage of Wrinkled  phenotype  - %

Percentage of smooth phenotype - %

a. the production of carbon dioxide through the process of photosynthesis

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
