PPT-Meiosis and Mendel Biology 1 Chapter 6

61 Chromosomes and Meiosis Cells can be divided into 2 major groups Somatic body most of body tissue and organs Germ found in reproductive organs develop into gametes Gametes are sex cells ova eggs amp spermatozoa sperm. (Body Cells). (Sex Cells). Examples of . somatic (body) cells:. spleen, kidney, eyeball. . The DNA in these cells are NOT passed on to your offspring!. Examples of . gametes (sex cells): . ova/egg and sperm. Mendelian inheritance has its physical basis in the behavior of chromosomes. You Must Know. How the chromosome theory of inheritance connects the physical movement of chromosomes in meiosis to Mendel’s laws of inheritance. Sexual Life Cycles. modes of reproduction. diploid/haploid and meiosis. meiosis I and meiosis II phases. key differences between mitosis and meiosis. variation in position of meiosis in life cycles. why sex?.

Stu Feinstein. Week 18 notes. Monday/ Tuesday . Warm-Up. What is a chromosome?. What is one segment of DNA called?. What is genetics? . Agenda. Section 10.1 (Mendel’s Laws of Heredity) Lesson & Notes. “Such a site would search like Google, recommend like Amazon, vet like . Consumer Reports, . annotate like. Wikipedia. . Done well, this interface would provide a core of information, tools, and networks for undergraduate biology educators.”. Cell Cycle, Mitosis and Meiosis. SC.912.L.16.17. Goals: Compare and contrast mitosis and meiosis and relate to the process of sexual and asexual reproduction and their consequences for genetic variation.. The . Work of . Gregor. Mendel. Genetics. :. The scientific study of heredity. (Is now at the core of a revolution in understanding biology.). Gregor. Mendel. : Was an Austrian Monk, who was in charge of the monastery garden. He was the first person to trace the characteristics of successive generations of a living thing (pea plants).. SC STANDARD B 4:. The student will understand the molecular basis of heredity.. Essential Question. How does segregation of alleles contribute to genetic variation?. Origins of Hereditary Science. Mendel” Breeding Experiments. Life Cycles. Overview: Variations on a Theme. Living organisms are distinguished by their ability to reproduce their own kind. Genetics . is the scientific study of heredity and variation. Heredity . multiplication. is the same thing as . division. …. 2006-2007. Making New Cells. Making New DNA. Where it all began…. You started as a cell smaller than . a period at the end of a sentence…. And now look at you…. Illustrate the steps of meiosis. Describe the roles of crossing over and independent assortment in meiosis . Explain the importance of meiosis to living organisms. Words to know. Crossing over. - the process by which genetic material is exchanged by non-sister chromatids during prophase I of meiosis. Abhinandan. . Chowdhury. (. ACh. ). Lecturer. Dept. Biochemistry & Microbiology. North . South University. Dhaka, . Bangladesh. Email; . abcnsuedu@gmail.com. Website: . www.abhinandanchowdhury.weebly.com. Essential Idea: . Meiosis produces genetically-varied, haploid cells needed for sexual reproduction. 3.3.1 One diploid nucleus divides by meiosis to produce four haploid nuclei. Meiosis. . is a process that divides .
