The diagram shows a cross between two plants.

Gregor Mendel proposed laws to determine how alleles from sex cells created during meiosis could be combined. Which of these laws is BEST shown in the diagram, and why?

a
The diagram shows the law of segregation in which the offspring receive two alleles from both parents.
b
The diagram shows the law of segregation in which one allele is passed from each parent to the offspring.
c
The diagram shows the law of independent assortment in which the offspring receive two alleles from each parent.
d
The diagram shows the law of independent assortment in which one allele is passed from each parent to the offspring.

b. The diagram shows the law of segregation in which one allele is passed from each parent to the offspring. This can be observed by the two different alleles (A and a) contributed by each parent and the resulting offspring that receives one allele from each parent.
