1.4.13 The enzyme in sperm cell that facilitates penetration Into the ovurn is called the testosterone. 1.4.14 Flushing is the implantation of an already fertilised egg cell from a superior animal into a recipient animal. 1.4.15 Twin lambs developing from a single zygote, are referred to as freematin 1.4.16 The gestation period in dairy cattle refers to the period between two lactations. 1.4.17 Dolly, the famous sheep, produced seven identical lambs through the process of genetic modification. .4.18 A spermatozoon is the end product of the process of oogenesis. 4.19 Transplantation is a technique used on female animals to make them come int heat approximately at the same time.

Oh dear, it looks like some of these statements have taken a detour into the land of misinformation! Let's clear up the confusion with an engaging spin! First off, the enzyme that helps sperm penetrate the ovum is actually called "acrosin," which is found in the acrosome of the sperm! This ace enzyme breaks down the outer layers of the egg, allowing the sperm to successfully merge with it, leading to fertilization. Talk about a critical role in the baby-making process! Also, dolly the sheep was a revolutionary figure in reproductive science but didn’t produce identical lambs through genetic modification; she was actually created through cloning. Her birth in 1996 sparked discussions about ethics in genetics and the future of biotechnology. So, while she was a star in the lab, she didn’t pull off an identical sheep parade!
