Answer: i- fraternal or dyzygotic twins
ii- monozygotic twins
Explanation: dyzygotic twins develop when two separate oocyte are fertilised by two different spermatozoa. They are also referred to as nonidentical or fraternal twins. They can be of the same or different sex.
Monozygotic twins develop when one oocyte fuses with one spermatozoa and splits into two after fertilization. These twins are also known as identical twins as they will be of the same sex and have the same gene, blood groups and physical features. They may be of different sizes and often have very different personalities and characters.
