Answer:
RrYy is the genotype that is heterozygous for both seed shape and seed color. The traits here we are discussing are pea plant's seed color and shape.
Explanation:
A dihybrid cross is a cross in which two traits are simultaneously being studied. Here there are two traits under consideration that are seed shape and seed color. The seed shape can be round or wrinkled and seed color can be yellow or green. The round seed allele is dominant over yellow seed allele and the yellow color allele is dominant over green color allele.
As homozygous indicate both alleles of a gene are same in an individual and heterozygous condition indicates that both alleles of a gene in an organism are different.
Therefore the genotype of homozygous pea plants for seed color and seed shape can be RRYY or rryy respectively and genotype of heterozygous genotype will be RrYy respectively.

DNA has 3 components; phosphate, a sugar called deoxyribose (a 5 carbon sugar as opposed to the sugar in the picture which is a 6 carbon sugar - glucose) and a nitrogenous base (adenine, thymine, guanosine or cytosine). So if you look at those 3 pictures, the only one is the nucleotide that's part of the DNA.
