PPT-Heredity and Evolution

We have already discussed reproductive process in which you have seen that youngones are joined from parents when young ones off springs are produced by single parent then they are similar to their parents because they reproduce asexually. 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. . 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. Half Shaded = Carrier. 2.5.2 Heredity . and Gene Expression. 2.5.3 Genetic . Code. 2.5.4 DNA Structure. , Replication and Profiling. Follow-Me – . iQuiz. Q. What term is used to describe differences within a population with respect to features such as height?. GeneticsGeneticsGene: basic unit of Gene: basic unit of inheritance inheritance Two genes(or alleles) for Two genes(or alleles) for each characteristic: one each characteristic: one from father and on Chapter 17: Processes of Evolution. Early Beliefs. 19. th. century: discovered species shared many traits, but lived in different parts of the world. Problematic – species only looked similar on the outside, but inside were very different . Evolution. – when a species of plants or animals adapts to their environment in order to survive over a long period of time. Key points!. Species. Plants or Animals. Adaptations. In order to survive. . The process by which organism change over time. Based on science, not opinion.. Darwin. :. Evolution is descent with modification. Evolution. :. changes through time. Species accumulate difference. . The process by which organism change over time. Based on science, not opinion.. Darwin. :. Evolution is descent with modification. Evolution. :. changes through time. Species accumulate difference.
