Answer:
Similar maternal treatment in warmth and negativity because of their identical heredity.
Step-by-step explanation:
Identical twins (also known as monozygotic twins) occur when an egg is fertilized to form one zygote, but then divides into two separate embryos. Monozygotic twins appear in around 3 in 1000 deliveries worldwide, with all regions in the world having similar rates. However, the exact cause for the why the zygote splits is unknown. When a mother has identical twins, they usually receive similar maternal treatment because of their identical heredity.
