Answer:
75 are expected to have red flowers
Explanation:
Since red is the dominant trait (R), you only need one R allele to have the red phenotype (to appear red). To be white, you will need to have two r alleles.
This punnet square shows us that three out of four offspring will have at least one R allele in their genotype. This means that 75% of offspring will look red. If there are 100 total offspring, 75 are expected to be red.
