11.3 group quiz

Independent Assortment- Allele pairs that desperate independently during gamete formation
Incomplete dominance- One allele for a specific trait is not completely dominant than the other
Codominance- A single gene has more than 1 dominant allele
Multiple alleles- a set of 2 or more alleles
Polygenic Traits- phenotype influenced by more than one gene

2. Describe 2 inheritance patterns beside simple dominance.
A. Codominance
B. Incomplete dominance

Biology Lab-Dice Probability 

Hypothesis: We want to see what the probability is of rolling two regulation, 6 sided dice. We want to find out what combination will come up the most, we both believe it will be seven.

Controlled Variable: Each die has 6 sides, and we will be using 2 dice.

Manipulated Variable: Throwing of the dice.

Responding Variable: The combination of each roll of the 2 dice.

Procedure: 1. We will roll 2 dice 100 times

                   2. Then we will record the combination of each roll.

1. And then calculate the recorded numbers, and find what comes up the most.

Conclusion: The purpose of this experiment was to find the probability of rolling two dice. We set up a controlled experiment where we rolled two 6-sided dice 100 times. Our results from our experiment show that 8 was the most common number that came up, it has the 2nd most combinations of the numbers of the 2 dice. These results refuted our hypothesis because we said it would be 7, which has the highest probability since it has the most available combinations. Our experiment has no sources of error, you can't really go wrong with rolling dice.

Investigating Inherited Traits

Pre-Lab
1. The single double sided quarter represents the dominant and recessive alleles.
2. The probability in perfect would be 50-50 because it has 2 sides and only can land on one.
3. A coin toss is a good way to represent allele combinations because it is somewhat of a % on how and which combo is going to be.
5. No, because the genotype is the genetic characteristics while phenotype is the physical characteristics. They are 2 totally different characteristics.

Analysis and Conclusions
1. The possible genotypes would be from the male and female parents. Also it would be a hubrid.
2. I do supports that another group got the same genetically identical 'child' to us because it is a 33% chance that it is possible.
3. Nobody because in my class has the same parents as me which means my genotype is a one of a kind.
4. It is similar because there are always chances to get certain genotype from our parents. The model is different because some of these traits may never show up like in the diagram.

11.2 Group Quiz

Probability- Chances of an event occurring.
Punnett Square- A square that is used to view the chances of a certain genetic cross.
Homozygous- 2 identical traits for the same allele.
Heterozygous- 2 different alleles for the same trait
Phenotype- Physical traits
Genotype- Genetic make-up

Punnett Squares are use by predicting/ comparing the results of a genetic cross.

Lab Group Quiz

Genetics- study of heredity
Fertilization- When a male and female reproductive organs meet
True-breeding- if allowed to self-pollinate, they would be identical to the parent
Hybrid- Offspring from male and female with different traits
Allele- Different forms of a gene
Segregation- Separation of alleles during gamete formation.
Gamete- Sex cells

Genes are the traits that are passed down from generation to generation.
