What is the probability that a cross between a heterozygous dominant yellow-seeded pea plant and a green-
seeded pea plant will produce green-seeded offspring?

1:1

1:2

1:4

1:8

So, using S as yellow and s as green alleles, with a punnett square, we see that two of the four offspring would be green seeds. So, 2:2 is equal to 1:1, so that would be your answer. I included the punnett square I drew for extra help. Good luck!

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
