If red and white color flowers in mirabulus jalapa are crossed, the F1 generation will show:

Explanation

When red and white color flowers in Mirabilis jalapa (Four O'Clock Flower) are crossed, the F1 generation will typically display an intermediate phenotype, resulting in pink-colored flowers. This is due to incomplete dominance or blending inheritance, where neither the red nor white color allele is completely dominant over the other. In this case, the red color is typically controlled by the presence of a dominant allele (R), while the white color is controlled by a recessive allele (r). When the red and white flowers are crossed, the F1 generation will inherit one copy of the dominant red allele (R) from one parent and one copy of the recessive white allele (r) from the other parent. As a result, the F1 plants will have a heterozygous genotype (Rr) and exhibit an intermediate phenotype, which is pink-colored flowers.
