RC2 Pink Room-Chromosomal Mutations

What term is used to describe chromosome pairs that are identical in size and shape, with genes for the same characteristics at corresponding places?

• diploid (2N)

• haploid (N)

• homologous chromosomes

• karyotype

What does the term "haploid" refer to?

• A cell with two sets of homologous chromosomes

• A cell with one set of chromosomes and a single set of genes

• A condition where an organism has extra sets of chromosomes

• A chromosomal abnormality with only one copy of a chromosome

What is nondisjunction?

• A mutation where a chromosome piece breaks off and reattaches in reverse

• A condition with an extra set of chromosomes

• The most common error in meiosis where homologous chromosomes fail to separate

• A chromosomal abnormality with only one copy of a chromosome

What is polyploidy?

• A cell with a single set of chromosomes

• A condition in which an organism has extra sets of chromosomes

• A mutation involving the loss of a piece of a chromosome

• A chromosomal abnormality where a diploid organism has only one copy of one of its chromosomes

What is a karyotype?

• A mutation involving a piece of a chromosome that breaks off and reattaches

• A condition with an extra copy of a chromosome

• A picture of the chromosome pairs of a cell arranged by size and shape

• A type of mutation involving the loss of a piece of a chromosome

A mutation involving a piece of a chromosome that breaks off and reattaches in a reverse orientation

• nondisjunction

• inversion mutation

• deletion mutation

• translocation mutation

A mutation in which one part of a chromosome breaks off and attaches to another

• translocation mutation

• deletion mutation

• inversion mutation

• nondisjunction
