Ploidy typically involves an individual having:

Specific additional or missing chromosomes (e.g. trisomy 21)

The wrong number of complete chromosome sets in all cells (e.g. triploidy)

A small inversion within chromosome 21

Robertsonian translocation

Refers only to abnormal sex chromosomes

Multifactorial diseases typically:

Are caused by a single mutation

Involve chromosome rearrangements

Lead to spontaneous miscarriage

Present in early childhood

Significantly affect adult populations

When studying an inherited phenomenon, a geneticist discovers a phenotypic ratio of 9:3:3:1 among offspring of a given mating. A possible explanation for this is a two locus-two alleles at each locus system that exhibits:

Epistasis

Linkage

Pleiotropy

Independent assortment

The phenomenon in which genes on the same chromosome are separated from each other during meiosis and new combinations of genes are formed is known as:

Leber's hereditary optic atrophy is caused by a mutation in:

Chromosome 12.

Chromosome 18.

Chromosome 21.

Mitochondrial DNA.

In humans, many more males are affected by Duchene muscular dystrophy than females and these affected males typically come from unaffected parents. The likely inheritance pattern is:

Autosomal dominant

Autosomal recessive

Mitochondrial

X-linked

Chiasmata occur between which of the following?

Sister chromatids

Any two chromatids

Non-sister chromatids

Maternal chromatids

If an affected male has affected daughters and sons in about the same number as unaffected daughters and sons, the trait is likely to be an:

X-linked dominant trait

Autosomal recessive trait

Autosomal dominant trait

X-linked recessive trait
