Deletion Mutation
occurs when a fragment of a chromosome breaks off and returns to the correct place on the original chromosome, but with the genetic loci in reverse order
Inversion Mutation
occurs when a broken piece from one chromosome becomes attached to a different, nonhomologous
chromosome
Translocation Mutation
is a type of chromosomal abnormality in which a
chromosome becomes longer because it ends up with two copies of a particular chromosome fragment

your normal cell, somatic cells
Diploid

* In humans, this is sperm and eggs, aka gametes
Haploid

Polyploidy
states that all genes are located on chromosomes
Chromosome Theory of Inheritance
the basic unit of information
affecting a genetic trait
Gene
different versions of a given gene
Alleles
any change in the DNA
sequence that makes up a gene
Mutation
physical location of a gene on a chromosome
Locus
Two alleles at a locus are different
Heterzygous
Two alleles at a locus are identical
Homozygous
bb=?
Homozygous Recessive
