Null hypothesis= no changes between populations or groups
Alternative hypothesis= a change between populations or groups.

What is an allele?
An allele is an alternative version of a gene

What is the differences between veins and arteries?
Veins carry blood to the heart and arteries carry blood away from the heart
100
What charge does DNA have?
Negative
200
What is meiosis?
The division of gametic cells.

When do accept a null hypothesis?
When do we reject a null hypothesis and accept the alternative hypothesis?
Accept a null hypothesis when X^2 or T-Value is less than the table value
Reject the null and accept the alternative when the X^2 and T-Value is greater than the table value

What is phenotype and genotype?
Phenotype is the collection of observable traits. Genotype is the genetic make-up

Systolic Pressure is?
Diastolic Pressure is?
Systolic= arterial pressure at the peak of ventricular ejection
Diastolic= arterial pressure during ventricular relaxation
200
What direction will the DNA tend to move during gel electrophoresis?
Towards the positive side

Mitosis produces 4 haploid or 2 diploid daughter cells?
Meiosis produces 4 haploid or 2 diploid daughter cells?
Mitosis= 2 diploid
Meiosis= 4 haploid

Homozygous is.... and Heterozygous is....
Homozygous= two identical alleles for a particular gene
Heterozygous= two different alleles for a particular gene

What are the steps of mitosis? And what is cytokinesis?
Steps of mitosis are= prophase, metaphase, anaphase, and telophase
Cytokinesis= division of the cytoplasm

If my T-value is 0.23, I have 5 degrees of freedom, and a table value of 0.17 with 5 degrees of freedom. Do I accept or reject my null hypothesis?
Reject

The allele for free ear lobes (F) is dominant to the allele for attached ear lobes (f). Suppose that a woman with genotype (ff) marries a man with a genotype (FF). Predict the phenotypic and genotypic ratio of their inbred F2 offspring.
See work on the board

What is occuring during the 3 phases of Interphase?
G1: Growth
S: Growth and DNA synthesis
G2: Growth and final preparations for division

The X-linked gene causing hemophilia in humans is controlled by two alleles: the normal allele (X+) is completely dominant to the hemophiliac allele (Xh). Suppose that a hemophiliac woman marries a normal man. Predict the genotypic and phenotypic ratio of their inbred F2 offspring.
Work this out on the board.
