Question

In the following image, which symbols (genotypes) represent the genotypes involved in the cross that produces the F2 generation of pink flowers? 
In this case, the dominant genotype is RR (red) and the recessive genotype is rr (white). The pink color appears to be an intermediary phenotype between the dominant and recessive parents. Therefore, a heterozygote (Rr), which contains both a dominant and a recessive allele, will display pink flowers.

The dominant RR (red) and recessive rr (white). The color pink seems to be an intermediary between the dominant and recessive parent. Thus a heterozygote (Rr) that contains both a dominant and recessive gene will have a pink color.

Your answer should be Rr x Rr. But i'm not completely sure so check with a teacher or parent.

Rr × RrExplanation: Gregor Mendel, the father of Genetics, performed several experiments that led to the principles that govern heredity. He discovered that; an organism receives two forms of a gene called ALLELE, from each parent. According to his law of dominance, he also discovered that an allele is capable of masking another for a particular trait. He called the allele that masks or is expressed DOMINANT allele while the allele that is masked RECESSIVE allele. But in exception to this rule, genetic scenarios have occured.For example, in cattles, where the allele for red hair (R) is not dominant or recessive to the allele for white hair (r), instead, they are both and equally expressed in the offspring. This genetic scenario is called CO-DOMINANCE. In cattles, purebred red cattles (RR) i.e. homozygous or having identical alleles crossed with purebred white cattle (rr) i.e. also homozygous, will result in F1 Roan cattles (Rr), which is an hybrid or heterozygote i.e. combination of two different alleles. The roan cattle expresses both the phenotype of the parents i.e. possesses both red and white hairs.To get the F2 offsprings/generation, the F1 offsprings are self crossed i.e. the hybrids are crossed together Rr × Rr.

Rr x Rr I think that's right but I'm not completely sure you might want to ask a parent or teacher to check

Rr x Rr i think thats right
