How does twinning occurs during sexual reproduction?
Answers
Answer:
Identical twins develop from a single fertilized egg. Shortly after the egg cell and sperm cell join, the zygote splits into two parts. Each new part is an identical copy of the original. Each has identical genetic material.
Explanation:
Answer: Twins are two offspring produced by same pregnancy. Non-identical twins results from two fertilised eggs when get implanted in the uterus wall at the same time. Identical twins occur when a single egg is fertilised to form one zygote which then divides into two separate embryos.
Explanation: There are two types of twins :
Identical twins: the fertilisation of one egg occurs. And shortly after the fusion takes place the zygote splits into two parts that give rise to two same individuals.
Non- identical twins: sometimes {very very very rare cases} ovaries release two eggs which get fertilised and give rise to two different individuals .
