Based on Morgan’s nomenclature of fruit flies, the dominant fruit fly is also considered this Back Wild type

This is the ratio that Morgan expected to see of the four phenotypes in his fruit fly experiment Back 1:1:1:1

These are the type of genes that were discovered through Morgan’s experiments Back linked

This are the traits that Morgan learned were linked to one another Back Body color and wing type

These are the phenotypes of the flies that were used to perform a testcross that revealed the presence of linked genes Back Gray, normal wings; black, vestigial wings

This is the law that states that gametic chromosomes may be split up causing the resulting alleles to separate from each other Back Law of segregation

This occurs when two or more genes control the same trait Back Polygenic traits

This occurs when one gene controls multiple traits Back pleiotropy

This takes place as a result of methylation of the genome Back epigenetics

This is when different genes interact with one another to produce a particular phenotype Back epistasis

codominant blood type Back AB

red + white = pink Back Incomplete dominance

different forms of a gene Back allele

three most common sex linked recessive conditions Back Colorblindness, hemophilia, muscular dystrophy

Gender more likely to have sex-linked recessive conditions Back male

These are all of the possible phenotypes associated with blood Back A, B, AB, O

If you have type AB blood, then you have antibodies for these blood types Back None of them

This is what determines whether your blood is positive or negative Back Rh factor

The blood type that is codominant is AB. This means that you will see these for each blood type on the surface of the blood Back antigens

If a person that is heterozygous for type B blood, these are the possible blood types they can receive in the event of a transfusion Back B,O

This is caused by the improper separation of chromosomes Back nondisjunction

This is when two species form a new species that have the total chromosome number of both of the species Back allopolyploidy

This results in the duplication of all of the chromosomes in an organism by itself Back autopolyploidy

This is a condition that results in females potentially becoming sterile Back Turner syndrome

This can cause many different disorders resulting from monosomy and trisomy Back aneuploidy

This the number of categories of data minus 1 Back Degrees of freedom

If your chi-square value is greater than the value on the chart, then you will do this to your null hypothesis Back reject

If you have a large chi-square value, then your observed and expected values are Back Far from each other

A population of 200 people results from heterozygous A parents and type AB parents. Here are the numbers for each phenotype: I A I A – 60I A i – 54I A I B – 36 I B i - 40 Back 8.24

Number of degrees of freedom and whether or not you accept or reject the null hypothesis on the last question Back 3, reject

This is what happens when histones are loosened Back acetylation

This is what takes place when one gene codes for multiple traits Back pleiotropy

This is what occurs when multiple genes control the same trait Back Polygenic traits

This is what methyl groups do to DNA Back Prevent transcription

The interaction between genes do not have to be on the same locus in this process Back epistasis
