Mllerian duct system to degenerate d. indifferent gonad to become an ovary e. indifferent gonad to become a testisWhich of the following does not directly contributeto variation in traits among the offspring of sexualreproducers?a. Crossing over during meiosisb. The union of gametes at fertilizationc. Equal distribution of chromosomes into gametesd. Alleles on homologous chromosomese. MutationGiven the table below give the difference between the number of parents involved and gamtes in asexual and sexual reproduction. Explain it thoroughly. Characteristics Asexual Reproduction Sexual Reproduction Number of parents involved Gametes
- One evolutionary advantage of sexual over asexualreproduction is that it produces .a. more offspring per individualb. more variation among offspringc. healthier offspringIn which of the following does fertilization occur outside the body? a. in vitro fertilizationb. gamete intrafallopian transferc. surrogate mothersd. All of these are correct.Why does asexual reproduction disadvantageous? * It takes time and energy to find a mate and reproduce. No answer Both A and B Low genetic diversity means susceptibility to diseases Fewer offspring are typically produced.
- Which of the following will result in identical twins?a. fertilization of two eggs by two different spermb. division of a zygote into two masses before differentiation has begunc. fertilization of two eggs by the same spermd. fertilization of one egg by two different spermWhat is the basis for the tremendous genetic diversity resulting from sexual reproduction?a. independent assortment during gamete productionb. crossing-over and shuffling of linked genes during meiosisc. random fertilizationd. all of these choicesWhich of the following cells canundergo meiosis?a. the diploid body cells of an animalb. haploid gametesc. germ cells
- Without SRY expression, an embryo will develop ________.a. male reproductive structuresb. female reproductive structuresc. no reproductive structuresd. male reproductive structures 50 percent of thetime and female reproductive structures 50percent of the timeIdentify each of these statements as ones that describe asexual reproduction (A),sexual reproduction (S), or could describe both (B) forms of reproduction. Writeyour answer on the space provided before each number.B= BothA= Asexual ReproductionS= Sexual Reproduction1. organism does not need a mate to reproduce2. takes some time to create offspring-3. the offspring are not the exact copy of their parent/s4. it is a quick process5. does not need to develop special cells for reproduction6. environmental changes affect all individuals-7. may only be able to reproduce with a limited number or may notreproduce at all_8. offspring are reproduced9. characteristics are passed down to the next generation10. many new organisms are created in a short period of time11. dogs and cats reproduce this way12. amoeba, yeast and bacteria reproduce this way.13. plants reproduce this way14. production of gametes is necessary15. its purpose is the survival and continuity of speciesWhich one is NOT a prezygotic barrier to successful reproduction? (i.e. all of them are prezygotic barriers except one) reproductive/genital parts do not match appropriately chromosome mis-match so the offspring are sterile mutation in courtship rituals mutations in the timing of reproduction
