Two examples of radioisotopes that can be used are carbon-14 to determine the age of fossils. Second, we can use iodine-131 to treat thyroid disease.
The answer is to the problem is false
Always start with the genotypic ratios, because they'll be the same. Since hidden variation is popping out, you can assume that both of the parents are heterozygous. The problems you get will be the F2 ratio of the cross between two homozygous individuals.
1:2:1 is the genotypic ratio for one locus. AA:Aa:aa.
1:2:1 is the phenotypic ratio for incomplete dominance. Incomplete dominance means that the heterozygote expresses differently from either homozygote.
3:1 is the phenotypic ratio for complete dominance.
2:1 is the phenotypic ratio for lethal recessive.
The plants absorb light energy into chemical energy. This energy is used by the plant for fuel. The byproduct of photosynthesis is Oxygen. That is why plants are so beneficial for air quality
