PPT-HEREDITY AND EVOLUTION PREPARED BY:JEHANGEER HAMEED

10 th class Variations in organisms mainly occur during sexual reproduction Because of mutations caused by errors in DNA replication Thus no two Offsprings are identical to each other Other causes of such variations. Chapter 4. 7. th. Grade Science. Mendel’s Work. ______________ - “Father of Genetics”. A priest that conducted experiments in his garden that revolutionized the study of heredity.. ___________ - the passing of physical characteristics from parents to offspring. What did Mendel Observe?. How do alleles affect inheritance?. Heredity. The passing of physical characteristics, or traits from parents to offspring.. VOCABULARY. Genetics: The study of Heredity (passing of traits from parent to offspring). For each question you missed, write down the entire correct answer (not just the letter) and where it is at in the textbook or notes, and what it says about it.. . Example:. Question 3. Soma is the correct answer. Found in notes. Soma is the main body of the neuron. . (Fundamentals of Genetics). Chapter 9. Heredity. The transmission of characteristics from parent to offspring. . Trait (allele)- variant of a characteristic. Mendel observed 7 characteristics of pea plants.. Theories of Inheritance. Chapter 7. Key Concepts. Neither Darwin nor Wallace knew how variation could be produced in Nature. . . What do we attribute this to now? . The accepted theories of inheritance were the . Traits. - Characteristic, quality, or feature that distinguishes an organism. Genetics. /Heredity. - . The passing on of traits from parent to offspring. Acquired Trait. - Trait that is learned or obtained through experience or practice.. A mechanism for change in populations.. Any change in the . inherited . traits within a population across generations. Individuals better adapted to their environment tend to survive and . produce more offspring. Trait. a characteristic that an organism can pass on to its offspring through its genes. . Offspring. The product of reproduction; a new organism produced by one or more parents (ex. Human baby). Chromosome. Mechanisms of concerted evolution. Unequal cross-over. Gene conversion: non-reciprocal transfer of information between homologous sequences; the main mechanism invoked to explain concerted evolution. Chapter 12. I. Pedigree. Graphic representation of genetic inheritance. (Look at Fig 12.1 and 12.2). I. Pedigree. Circle = female. Square = male . Shaded = shows trait being studied.
