  1. Genetics genética

  2. Agenda • Test question practice • Do Now • Activity- Pedigrees and the Russian family • Notes • Family Study (bring in family photo) • Exit ticket

  3. Do Now Match up the following: • Oldest form of life. Simple and single- celled multicellular organisms. Prokaryotes. 2. Have a nucleus and membrane unicellular bound organelles. 3. type of reproduction that requires only 1 asexual parent. Budding, fragmentation, and regeneration are examples.

  4. Do Now 4. A scientist looks at a cell and says it is a plant cell. List 2 reasons why he said it was a plant cell.

  5. hazlo ahora Match lo siguiente:1.Más antigua forma de vida. Sencillo multicellular y simple unicelulares organismos. Procariotas. 2. Tener un núcleo y la membrana unicellularorgánulos unidos . 3. tipo de reproducción que requiere sólo 1 asexual padre . En ciernes , fragmentación y regeneración son ejemplos .

  6. hazlo ahora 4. Un científico que mira a una celula dice que es una célula vegetal. Lista 2 razones por las que dijo que era una célula vegetal.

  7. Copy/copie: Gifts From Your Parents Learning Target I understand that some traits are inherited and can be traced in family lineage, and that some traits are not always expressed in each generation. Some traits can be acquired while others are genetically determined. Objetivo de AprendizajeEntiendo que algunos rasgos son heredados y pueden ser rastreados en el linaje de la familia , y que algunos rasgos no siempre se expresan en cada generación . Algunos rasgos pueden ser adquiridos mientras que otros están determinadas genéticamente.

  8. Homework: Bring in a coin for next class’ experiment! Traiga una moneda para la próxima clase "experimento !

  9. ¿Cómo se producen las similitudes en las familias? How do similarities in families occur?

  10. Who invented genetics? Johann Gregor Mendel (1822-1884) Father of Genetics Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

  11. ¿Quién inventado geneticas? Gregor Mendel , a través de su trabajo en las plantas de guisantes , descubrió las leyes fundamentales de la herencia. Dedujo que los genes vienen en pares y se heredan como unidades distintas, una de cada padre. Mendel dio seguimiento a la segregación de los genes de los padres y su aparición en la descendencia como rasgos dominantes o recesivos .

  12. Pedigrees allele- one alternative form of a gene (mom gives you 1, dad gives you 1) autosomal- the sex does not determine the gene recessive- a trait that is expressed only when dominant allele is not present bb, not Bb dominant- only need 1 allele to be expressed

  13. un alelo- una forma alternativa de un gen ( mamá te da 1 , papá te da 1 )autosómica- el sexo no determina el genrecessive- un rasgo que se expresa sólo cuando alelo dominante no no está presente bb, Bbdominante- sólo necesita 1 alelo ser expresadas

  14. allele/alelo These are the variety of forms of the gene Estos son la variedad de formasdel gene During cell division, these pull apart. mom gives 1, dad 1 Durante la división celular , éstos se separan . mamá da 1 , papá 1

  15. Directions Turn to page 417. Read 417-419. Make sure you read the purple box “A Royal Tragedy.” Answer the questions on the following slide. Instrucciones: Abre a la pagina 419. Mire a la pedigri de la familia. Copie y respueste las preguntas en el “slide” # 21.

  16. How did the young czarvitch come to have hemophilia? • How is it possible that the mother and father showed no signs of the disease? 3. Suggest some traits that people acquire throughout their lifetime. What is the difference between acquired traits and inherited traits? 4. How might cultural practices have influenced the frequency of hemophilia occurring among the czar’s family?

  17. Instrucciones En el siguiente “slide” copie las preguntas y trabaje con un/una companero(a) para responder.

  18. 1. ¿Cómo surgió la joven llegado a tener hemofilia?2. ¿Cómo es posible que la madre y el padre no mostraron signos de la enfermedad?3. Sugerir algunos rasgos que las personas adquieren a lo largo de su vida. ¿Cuál es la diferencia entre los rasgos adquiridos y rasgos heredados ?4. ¿Cómo podría prácticas culturales han influido en la frecuencia de la hemofilia se producen entre la familia del zar ?

  19. Draw a picture that represents: Haz un dibujo que representa Inherit- Pedigree-

  20. Cleft Chin Camptodactyly bent pinky

  21. Mid finger hair

  22. Traits you might investigate: ear lobes: attached or detached double jointed freckles hitch hiker’s thumb tongue rolling hand writing style hair on fingers eye color widows peak dimples cleft chin

  23. Exit Ticket • How can you distinguish acquired traits from inherited ones? (Hint: can scars be inherited?)

  24. Why does eating asparagus make your pee smell? Asparagus contains a sulphurous compound called mercaptan (which is also found in rotten eggs, onions and garlic). When your digestive system breaks down mercaptan, by-products are released that cause the strange smell. The process is so quick that your urine can develop the distinctive smell within 15 to 30 minutes of eating asparagus. Not everyone suffers this effect; your genetic makeup may determine whether your urine has the odor -- or whether you can actually smell it. Only some people appear to have the gene for the enzyme that breaks down mercaptan into its more pungent parts.

  25. Family Study Divide your paper into 4 squares. Choose 4 traits to investigate in your family. Interview your family and make observations of traits that family members have. Write your results in each box. Dig deeper- ask about your great grandparents, great uncles. Did they have any unique traits or diseases?

  26. Extra Credit! 10 points. Have your family buy asparagus and cook it for dinner. Eat a couple pieces of asparagus (at least 3). It usually takes about 15-30 minutes for your body to break down the chemical in asparagus and for it to “smell-up” your pee. After everyone goes to the bathroom after dinner, record if they could smell it or not.

  27. What you need to turn in for extra credit • who could and couldn’t smell it? • explain why pee smells after asparagus? • explain why your family/guardians CAN or CANNOT smell it. • Is it an acquired trait or inherited trait.

  28. Study Pedigrees
