In tomato plants, round is dominant to elongated fruit and smooth skin is dominant to fuzzy skin. In a test cross between a heterozygous tomato plant with round fruit shape and smooth fruit skin and a homozygous recessive plant with elongated fruit shape and fuzzy skin, the following numbers of offspring were counted: 246 smooth, round 24 smooth, long 24 fuzzy, round 266 fuzzy, long Are these results consistent with the hypothesis that these genes are independently assorting?

Angiosperm Reproduction

The process of sexual reproduction in flowering plants is known as angiosperm reproduction. In flowering plants, reproduction begins with pollination, or the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (pistil), and ends with fertilization of the female gametes (egg), which produces a zygote, which then grows to become a mature plant.
