Group Review

Rules for Group Review

You must work with your group.Only one person may answer for your

group.You may not talk during other groups’

turns or your group will lose points.If you repeat an incorrect answer, your

group will lose points.You may not use anything during Group

Review except your brains.If voice levels cannot be controlled, we

will stop playing and instead have a pop quiz.

Bonus Round!!!!

At the end of each scoring round, there will be an opportunity for “Garbage Ball”.

For this, one member from each team will be given the chance to try to shoot the Garbage Ball into the small garbage can.

If the team member makes the shot, the team earns that round’s points as extra points.

In the case of excessive cheering, teams can be penalized.

In the case of excessive insulting, teams can be penalized.

Mitosis and Meiosis

Noriko is studying a plant species she found in a forest. She collects leaf samples from a large parent plant, and from the smaller offspring that are growing next to it.

A. The offspring were produced sexually, and two parents were required.

B. The offspring were produced asexually, and two parents were required.

C. The offspring were produced sexually, and only one parent was required.

B. meiosis

Heredity and Genetics

What is the relationship between an individual’s chromosomes and the genes for earlobe attachment?

B. The chromosomes for earlobe attachment are located on the genes of each cell.

C. The genes for earlobe attachment come from one parent and the chromosomes for earlobe attachment come from the other.

D. The chromosomes for earlobe attachment are made up of cells.

A. The genes for earlobe attachment are located on the chromosomes of each cell.


DNA contains genes that provide instructions for inherited traits. What is the relationship between the genes and chromosome?

A. All would have two recessive alleles and white flowers.

B. All would have two dominant alleles and purple flowers.

C. All would have one recessive allele, one dominant allele, and white flowers.

D. All would have one recessive allele, one dominant allele, and purple flowers.

D. All would have one recessive allele, one dominant allele, and purple flowers.

Goombas

http://www.youtube.com/watch?v=_2PVvFe-Jqg&safe=active




Goombas are one of the Super Mario Brothers most recognizable enemies. Recently scientists in the Mushroom Kingdom, where Goombas live, have been performing experiments on their DNA and heredity. It turns out that Winged Goombas carry a dominant allele for wings, while members of the population with no-wings are homozygous recessive.


What is the phenotype for each of the following genotypes in Goombas…

GG:.......wings



Gg:.......wings



gg:.......No wings


What are the 4 possible genotypes for offspring if a Winged Goomba (Gg) and a Winged Goomba (Gg) reproduced? Create a Punnett Square if you need to.

.......GG, Gg, Gg, gg


Based off of the last question, if the P1 Generation are Winged Goomba (Gg) and a Winged Goomba (Gg), what is the probability of offspring being born without wings?

.......25%

Final Question!!!!

Talk to your group to decide how many points you want to wager.

If you get the Final Question correct, you will add the wagered points to your score.

If you don’t, you will lose the points.

Final JeopardyGenetics and Heredity

Everyone in Squidward’s family has light blue skin, which is the dominant trait for body color in his hometown of Squid Valley. His family brags that they are a “purebred” line. He recently married a nice girl who has light green skin, which is a recessive trait.

Create a Punnett square to show the possibilities that would result if Squidward and his new bride had children. Use B to represent the dominant gene and b to represent the recessive gene.

What is the probability of having green skinned offspring?

0%
