Fraternal twins are resulted.
Two ova are fertilised by two sperms thus forming two different zygotes known as dizygotic contrary to only one zygote splitting into two to form genetically identical twins.
Fraternal twins are non-genetically identical twins.
Hope it helped!
In my opinion I don't think it is because we are who we are and it doesn't need to be messed with.
Answer: The cells in a cytoplasm of the organellesare called cytosol.

Answer:
The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.
Explanation:
An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.
The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:
- <em>Both dominant alleles: PT
</em>
- <em>One dominant and one recessive allele Pt or pT
</em>
- <em>Both recessive alleles: pt
</em>
Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.
Answer:
A bottom-up system concentrates attention on how resources (space and nutrients) influence higher trophic forms , whereas a top-down system focuses on interactions at top level consumers (predators) and their prey influence on lower trophic forms.
