In pea plants, yellow seed color (Y) is dominant and green seed color (y) is recessive. Based on the Punnett squares, what are the chances that the offspring in the second generation will have green seeds? First Generation Y Y

There is a
% chance that the offspring will have green seeds.

-The P generation has yellow and green seeds.

-The F1 generation has all yellow seeds.

-The F2 generation has yellow and green seeds.

Explanation:

Yellow seed color (dominant)  

Green seed color (recessive)  

P generation: In Mendel's experiments the parental generation.  

Yellow seed color

F1 generation: In Mendel's experiments the offspring of the P generation

Yellow seed color and

Green seed color

F2 generation: In Mendel's experiments the offspring of the F1 generation

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
