Most females have one X and one Y (XY) sex chromosome.

To calculate the percentage of people who have a particular allele, population studies are conducted to collect data.

Humans share common ancestors. Therefore the DNA STR profile of all humans is the same.

mtDNA is used to trace ancestry through the female line.

Except for identical twins, no two people on earth have the same:

People are always shedding cells. Therefore DNA can be recovered from:

The term that describes a picture of homologous pairs of human chromosomes is

The 95 percent of noncoding DNA is involved in:

If one person has two alleles that are the same for a specific STR, then that person is considered to have:

James Watson and Francis Crick received the 1953 Nobel Prize for their work on describing the structure of DNA as:

Which chromosomes have the same shape and contain the same genes?

DNA in chromosomes is called

Alternate forms of a gene are called

(GAAT) (GAAT) (GAAT) (GAAT) is an example of:

The total amount of DNA in a cell, which is contained in the cell's nucleus (nuclear DNA) and mitochondria (mtDNA), is called the human:

Approximately how many base pairs are in the human body?

Which method is used to identify different STR markers?

Ninety-five percent of DNA is non-coding. What term describes non-coding DNA that acts as genetic "on-an-off" switches?

_____ are the material used to isolate and cut DNA.
