PPT-Errors in mitosis or meiosis can results in changes in phenotype

Alteration of Chromosome Structure Breakage of a chromosome can lead to four types of changes in chromosome structure Deletion removes a chromosomal segment Duplication repeats a segment Inversion . Neither. Both. Meiosis. Mit. , Mei, Both, Neither. Centrosomes. replicate twice. Meiosis. Centrosomes. replicate twice. Mit. , Mei, Both, Neither. Produces gametes in plants. Neither. Produces gametes . Each organism must inherit a single copy of every gene from each of its “parents.”. Gametes. are formed by a process that separates the two sets of genes so that each gamete ends up with just one set.. Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:.

Answer the following questions on the back of your review sheet.. Meiosis The formation of gametes (sex cells) Some Vocab Haploid ( n ): one set of chromosomes Reproductive cells are haploid (23 Chromosomes in humans) Eggs Sperm Diploid ( 2n ): a single . DNA molecule complexed with histone . proteins. DNA is organized within the nucleus as chromosomes. Each chromosome is comprised of subunits called nucleosomes: DNA + proteins. Chromosome numbering/naming. R. r. Source: plant-genetics.kais.kyoto-u.ac.jp. ATGGGCACTGCCACT. A chromosome is a single DNA molecule . complexed . with histone proteins. DNA is highly compacted: DNA + histone proteins = . chromatin. Standard: . recognize the significance of meiosis to sexual reproduction. . . [. BIO.6G. ]. describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms. Levels of Biological organization. Cells  Tissues. Tissues  Organs. Organs  Organ Systems. Organ Systems  Organisms . From zygote to Trillions of Cells. Zygote=Cell that forms when sperm and egg join. Gametes. are formed by a process that separates the two sets of genes so that each gamete ends up with just one set.. Chromosome Number. All organisms have different numbers of chromosomes.. A body cell in an adult fruit fly has 8 chromosomes: 4 from the fruit fly's male parent, and 4 from its female parent..
