sex chromosomes
A sex-determination system is a biological system that determines the development of sexual characteristics in an organism
point mutations
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base substitution, insertion, or deletion of the genetic material, DNA or RNA
crossing over
Chromosomal crossover is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes during sexual reproduction
syndromes
A syndrome is a set of medical signs and symptoms that are correlated with each other
frameshift
A frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three
recombination
Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent
DNA polymerase
In molecular biology, DNA polymerases are enzymes that synthesize DNA molecules from deoxyribonucleotides, the building blocks of DNA
