Question

At the time of fertilization, sperm head enters in the egg from

• A. Any where
• B. Animal pole
• C. Vegetal pole
• D. Lateral side of egg

Answer 1

The correct option is B Animal pole

The main function of fertilization is to combine the haploid sets of chromosomes from two individuals into a single diploid cell, the zygote. Sperm enters the egg at the animal pole. The animal pole consists of small cells, which divides rapidly, in contrast to the vegetal pole below it. The animal pole draws its name from its liveliness relative to the slowly developing vegetal pole.
