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.

Mendel’s Experiment. In the mid 19. th. century, a monk named Mendel studied how traits are passed from one generation to another.. Experimented on . garden peas. .. .  green pea plants reproduce sexually (produce gametes). 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. . Traits. Detached Earlobes . Tongue rolling. Dimples. Cleft Chin.

Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . With special thanks to. Kathrin Stanger-Hall. and. Jess Blum. University of North Carolina, Chapel Hill. Jean .

He discovered how traits were inherited. GENETICS. – study of heredity. HEREDITY. – the passing of traits from parents to offspring. Week 18 notes. Monday/ Tuesday . Warm-Up. What is a chromosome?.

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 . (And why was his work so important?). Gregor. Mendel. Gregor. Mendel was a monk who lived in the 1800s. Mendel’s Mind Wandered…. Mendel wondered how the same species of plants could have different characteristics. Meiosis is the. . type of . cell division by which . germ cells . (eggs and sperm) . are produced. . One parent cell produces . four . daughter cells. . Daughter cells have half the number of chromosomes found in the parent cell. These phenomena observed in Saccharomyces cerevisiae are highly conserved in eukaryotes, thus rendering yeast, which is easy to use, an essential model organism. Researchers identified and studied fun
