Unit: Reproduction Chapter: Human Reproduction Class: 12th Biology Presented By: Dr. Priyanka Patade REPRODUCTIVE EVENTS •Humans sexual reproduction, viviparous, unisexual. •Each sex has pair of gonads, reproductive duct and accessory structures. •Sex organs – Testis( paired) male , ovaries (paired) Gamete formation, hormones. • Puberty  1. Gametogenesis - formation of gametes (sperms/ ova) 2. Insemination - transfer of sperms into the female genital tract 3. Fertilisation - fusion of male and female gametes leading to formation of zygote 4. Implantation - development of blastocyst and its attachment to the uterine wall 5. Gestation -- embryonic development (from conception to birth) 6. Parturition-- delivery of the baby (child birth) Male reproductive system Located in pelvis region The Male reproductive system includes: a) A pair of testes  (in scrotum)  b) Accessory ducts, glands  (rete testis, vasa efferentia epidid...

Unit VII: Genetics Chapter 5 : Principles of Inheritance and Variation Class: 12th Biology Presented By: Dr. Priyanka Patade Terminology Genetics:  Genetics is the study of principles and mechanism of heredity and variation. Gregor Johann Mendel is known as ‘ Father of Genetics ’. Inheritance: It is the process by which characters are passed on from parent to progeny. It is the basis of heredity. Variation: It is the degree by which progeny differ from their parents. Variation may be in terms of morphology, physiology, cytology and behaviouristic traits of individual belonging to same species. Variation arise due to: ⤷Reshuffling of gene/chromosomes. ⤷Crossing over or recombination. ⤷Mutation and effect of environment. Terminology ✓ Genetics is the branch of life science that deals with the study of heredity and variation. ✓ Heredity is the transmission of characters from parents to their offsprings. ✓ Variation is the dif...
