2b- Chromosomal Mutation Review

When a segment of a chromosome breaks off.

When a segment of a chromosome breaks off, flips, and reattaches.

When a segment of a chromosome is copied or doubles.

When a segment of a chromosome breaks and attaches to a non homologous chromosome.

When entire chromosomes don't separate evenly during meiosis.

Translocation

Nondisjunction

Dublication

Inversion

Deletion

Deletion of genes on chromosome 4

The wrong number of chromosomes in the gametes

Increased variation of genes with no chance of disorders

More recessive traits expressed.

chromosomes lining up

"crossing over" of chromosomes

separation of chromosomes

chromosomes pulling apart

anaphase 1

prophase 1

prophase 2

telophase 2

RNA translation occurs in the smooth endoplasmic reticulum

Crossing over takes place in backterial cells

Crossing over produces genetically identical daughter cells

Crossing over provides genetic diversity in eukaryotic cells

Crossing over

Metaphase

Dna replication

Increases genetic variation

Reduces the diploid number to the haploid number

Increases the haploid number to the diploid number

Reduces the probability of mutations
