October 18, 2013 HEREDITY BASKETBALL CHALLENGE!!!! WHO IS UP FOR A LITTLE COMPETITION!!??!? James Brady Instructions for Editing Create a new Text box for the answer to the question. Click the basketball to return to the court Click on a basketball to get to a question Edit the question here text box Click the question check box to edit the answer page Repeat process for all the basketballs
Rules of the game Divide class into two teams, each team will have one half of the court. Click on a basketball to receive a question. If the question is answered correctly 100 points is awarded to the team. That team member can now try and make a basket by shooting the ball at the basket. If the shot is made you will hear a SWEET! from Napoleon Dynamite, and you will get to roll the multiplier dice. Take the number from the dice and multiply it by the 100 points from the correct answer. 100 points x a dice roll of 5= 500 points If the question is missed or the shot is missed return back to the court and use an X to mark out the last selected question. Teams alternate turns Brady's Basketball
An organism with two different genes is called a what?! Heterozygous
A plant with two tall genes is called a what. Example (TT) Use THREE WORDS!! HOMOZYGOUS PURE TALL
How would you define the word TRAIT?! Characteristics that an organism has. Examples: Hair Color, Eye Color
What would the offspring be if one parent is pure dominant and one pure recessive? Heterozygous Dominant
Describe a dominant gene... A dominant gene always shows up in the offspring. Represented by a capital letter. Can mask a recessive gene.
What word means to pass on traits to the offspring? HEREDITY
What are Genes in charge of? TO CONTROL THE TRAITS!
What is known as "the thread of life"? DNA
If two parents had the same genotypes of hair color and eye color but their offspring did not have either..what could you conclude? THEY ARE HETEROZYGOUS FOR HAIR AND EYE COLOR
How many combinations would there be if two parents are heterozygous for hair color (Pp)? THREE
What are the chances for inheriting a genetic disease if a parent is a carrier? ONE IN FOUR ALWAYS!! THIS MEANS THAT IF A FAMILY HAS ONE KID WITH A GENETIC DISORDER AND DECIDE TO HAVE ANOTHER KID, THAT CHILD WILL STILL HAVE A 1 OUT OF 4 CHANCE!
What does the offspring get from the female parent during sexual reproduction? ONLY ONE X, NOT TWO!!! REMEMBER, SHE NEEDS TO HOLD ONTO ONE!!
WHAT DOES PHENOTYPE MEAN? PHENOTYPE DEALS WITH THE PHYSICAL CHARACTERISTICS ONE POSSESSES.
What process allows for organisms to get their sex cells? HINT MITOSIS OR MEIOSIS?! MEIOSIS!!!!!!!
What do Punnet Squares show? GENES... Punnet Square show the possible combination of gene pairs for a given trait.
Let's say that there were two lakes. One lake has all sexually reproducing organisms and one lake has asexual organisms. We concluded that if a bad bacteria was introduced to the lake, that the sexually reproducing organisms would survive better. What would support this theory? SEXUALLY REPRODUCING ORGANISMS WOULD HAVE A VARIATION OF INHERITED CHARACTERISTICS!! THEY COULD SURVIVE DUE TO HAVING VARIATION!!!
In a species of lizard, green scales are dominant (S), while yellow scales are recessive (s). If a green lizard mates with a yellow lizard and produces 5 offspring, 4 of which are green and 1 of which is yellow, what must the genotype of the green parent be? EXPLAIN WHY! Ss, EXPLAIN WHY??!?!?
GIVE SOME EXAMPLES OF ASEXUAL REPRODUCING ORGANISMS. BACTERIA, STRAWBERRY PLANTS, MINT, ECT
If two parents had Brown Eyes (B), and one of their offspring had blue eyes, what would the parents be? A. Heterozygous blue B. Homozygous blue C. Heterozygous brown D. Homozygous brown HETEROZYGOUS BROWN OF COURSE!!
What did Mendel conclude after he crossed many pea plants? Think of the variation! THERE WAS A PATTERN OF INHERITANCE!!!
If I told you that an animal had 78 body cell chromosomes. How many chromosomes would be from the sex cell? Explain your answer! 39 Half the amount of body cell chromosomes.
Which chromosome controls what happens with sex-link traits?! X
What are two advantages of SEXUAL REPRODUCTION?! VARIATION ADAPT TO ENVIRONMENT ECT.
Name TWO DISADVANTAGES OF ASEXUAL REPRODUCTION NO VARIATION CAN'T ADAPT TO CHANGES IN ENVIRONMENT
What is one exception to scientitists being able to trace DNA back to ONE INDIVIDUAL. IDENTICAL TWINS
NAME FOUR VARIATIONS THAT MENDEL OBSERVED WHEN CROSSING PEA PLANTS. COLOR of peas SHAPE of pods Height of plant Color of Flower Shape of peas
DRAW A PUNNETT SQUARE TO REPRESENT a Heterozygous Dominant plant and a Homozygous Pure Recessive plant. T=Tall t=short DRAW:
WHAT ARE GENOTYPES?! Genes of an organism REPRESENED BY LETTERS: Example : Tt
What is an allele?! An allele is one pair of genes that determine a specific trait.
What did Gregor Mendel conclude from his results with crossing the Pea Plants?! PATTERN OF INHERITANCE!!
