Adhesion of male and female reproductive organs The formation of gametes by a reproductive organ formation of single cell during sexual reproduction by fusion of nuclei of male and female gamates. formation of single cell during sexual reproduction by fusion of nuclei of male and female gamates. 3 / 15 Characters that are transmitted from parents to ofspring during reproduction Only similarities with parents Only variations with parents Both similarities and variations with parents Neither similarities nor variations similarities due to sharing of chromosomes from both the parents variation due to mutuation ,genetic recombination similarities due to sharing of chromosomes from both the parents variation due to mutuation ,genetic recombination 4 / 15 The ability of a cell to divide into several cells during reproduction in Plasmodium is called Budding vision Reduction division Binary fission multiple fission Multiple fission Repeated division of an organism to produce many daughter cells simultaneously. Repeated division of an organism to produce many daughter cells simultaneously. 5 / 15 The number of chromosomes in parents and offsprings of a particular species remains constant due to: Halving of chromosomes during gamete formation Doubling of chromosomes after zygote formation Halving of chromosomes during gamete formation Doubling of chromosomes after gamete formation Halving of chromosomes after gamate formation Reduction division (meiosis) takes place during gamete formation. Reduction division (meiosis) takes place during gamete formation. 6 / 15 Choose the precise statement(s) on budding in yeast from the following: A parent cell divides into two or more daughter cells and here the parent identity is lost In this the elongated nucleus divides to form two or more daughter nuclei. A bud arises from a particular region on a parent body After detaching from the parent body the bud grows into a new independent individual Budding in which a bud arises from a particular region on a parent body. And after detaching from the parent body the bud grows into a new independent individual Budding in which a bud arises from a particular region on a parent body. And after detaching from the parent body the bud grows into a new independent individual 7 / 15 Which among the following diseases is not sexually transmitted? Syphillis Hepatitis HIV-AIDS Gonorrhoea Hepatitis is not a sexually transmitted disease. It is a water-borne viral disease compared to other options. Hepatitis is not a sexually transmitted disease.

The age at which the reproductive organs of boys and girls become non functional. The age at which the reproductive organs of boys and girls become functional. It is a process of fertilisation in boys and girls. None of these 12 / 15 In flowers,what is the female reproductive part called as? Pistil Or Carpel Ovaries Filaments Stigma 13 / 15 A pair of long convoluted tubes that carry ova or eggs from the ovary to the uterus is known as Tubectomy Callopian Tube Fallopian Tube All Of These 14 / 15 Which of the following is surgical method of birth control in females? Tubectomy Vasectomy Both 1 & 2 None Of These 15 / 15 Total number of chromosomes present in human beings are 46 23 24 48 Your score is 0% Restart quiz
