Welcome to your CIE A2 Inherited change During puberty, primary oocytes undergo meiosis to form: Oogonia Two secondary oocytes Two haploid cells Two polar bodiesWhich of the following is true regarding the process of meiosis I? Sister chromatids seperate to opposite ends of the cell. Most homologous pairs do not have any cross overs during prophase I. Sister chromatids in a cell undergoing meiosis are always identical. Chromosome number is reduced from diploid to haploid.Which of the following statements is true regarding the crossing over? Segments of DNA are traded between unrelated chromosomes. Most homologous pairs do not have any crossover events. A chiasma indicates that a crossover has occured. Crossing over occurs more often in male gametes than female gametes.A disease which is an example that displays the relationship between a gene, an enzyme and a human phenotype. Albinism Sickle cell anaemia Haemophilia Huntington's diseaseA man has haemophilia. Which statement correctly describes the inheritance of the gene causing the condition? He inherited the dominant allele from his father. He inherited the recessive allele from his mother. He can pass the dominant allele to a daughter. He can pass the recessive allele to a son.The site where male gametes are produced in flowering plants: Carpel Anthers Receptacle OvulesDuring oogenesis, oogonia divides by meiosis and stops at which stage? When they reach prophase I When they reach metaphase I When they reach telophase I When they reach prophase IIThe result of a male gemete from a pollen grain fusing with a female gamete inside an ovule of a flowering plant. Diploid pollen mother cell Haploid zygote Diploid zygote Embryo plantThe stage of meiosis where centromeres split and chromatids seperate. Metaphse II Prophase I Telophase I Anaphase IIDuring sperm production, diploid cells divide by mitosis to produce numerous diploid _______, which grow to form diploid ________. The first division of meiosis then takes place, forming two haploid ________. The second division of meiosis then produces haploid _______, which mature into spermatozoa. spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids spermatids, primary spermatocytes, secondary spermatocytes, spermtogonia spermatogonia, secondary spermatocytes, primary spermatocytes, spermatids primary spermatocytes, secondary spermatocytes, spermatogonia, spermatidsTime is Up!
