Answer:
The offspring of organisms that is reproduce through sexually are not genetically identical to their parents because the offspring contains genes from two parents.
Explanation:
Identical offspring is only formed when offspring is produced from one parent through asexual reproduction such as building, binary fission and fragmentation. In sexual reproduction, offspring is produced by the mating of two organisms i. e. male and female organism. That's why genes of offspring are different from their parents and offspring is not identical to parents.
The genotype depends if the purple flower is heterozygous dominant of homozygous dominant. But the total possible phenotypes available is 2, purple or red.
Well, when chromosomes cross over during prophase 1 of meiosis, the homologous pair of chromosomes exchange segments of DNA which happen to be the genes. So the significance of crossing-over during prophase 1 is that it adds genetic variation to sexually reproducing organisms.
