Non Mendelian Genetics, Karyotypes, Pedigrees & DNA FP Review

Front

What is DNA fingerprinting?

Back

A technique used to identify individuals based on their unique DNA patterns; no two people, except identical twins, have exactly the same DNA.

Front

How can you determine if a person is biologically female by looking at chromosomes?

Back

A person is biologically female if they have two X chromosomes (XX).

Front

What does a pedigree chart represent?

Back

A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors.

Front

How many X chromosomes do females have?

Back

Females have two X chromosomes.

Front

What is the genotype of a homozygous dominant individual?

Back

The genotype of a homozygous dominant individual is represented as 'AA'.

Front

What is the primary purpose of restriction enzymes in gel electrophoresis?

Back

Restriction enzymes cut DNA strands into various lengths for testing.

Front

What is a karyotype?

Back

A karyotype is an organized profile of an individual's chromosomes, used to assess chromosomal abnormalities.

Front

What is hemophilia?

Back

Hemophilia is a genetic disorder that impairs the body's ability to make blood clots, leading to excessive bleeding.

Front

What does it mean if a trait is recessive?

Back

A recessive trait is one that is only expressed when two copies of the recessive allele are present.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.
