replication ((genetics) the process whereby DNA makes a copy of itself before cell division)

meiosis; miosis; reduction division ((genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants))

expression ((genetics) the process of expressing a gene)

single nucleotide polymorphism; SNP ((genetics) genetic variation in a DNA sequence that occurs when a single nucleotide in a genome is altered; SNPs are usually considered to be point mutations that have been evolutionarily successful enough to recur in a significant proportion of the population of a species)

polymorphism ((genetics) the genetic variation within a population that natural selection can operate on)

position effect ((genetics) the effect on the expression of a gene that is produced by changing its location in a chromosome)

dominance (the organic phenomenon in which one of a pair of alleles present in a genotype is expressed in the phenotype and the other allele of the pair is not)

saltation ((genetics) a mutation that drastically changes the phenotype of an organism or species)

reversion ((genetics) a return to a normal phenotype (usually resulting from a second mutation))

gene mutation; point mutation ((genetics) a mutation due to an intramolecular reorganization of a gene)

monogenic (of or relating to an inheritable character that is controlled by a single pair of genes)

homozygous (having identical alleles at corresponding chromosomal loci)

recombination ((genetics) a combining of genes or characters different from what they were in the parents)

polyploid (of a cell or organism having more than twice the haploid number of chromosomes)

diploid (of a cell or organism having two sets of chromosomes or twice the haploid number)

haploid; haploidic; monoploid (of a cell or organism having a single set of chromosomes)

recessive ((of genes) producing its characteristic phenotype only when its allele is identical)

dominant ((of genes) producing the same phenotype whether its allele is identical or dissimilar)

translate (determine the amino-acid sequence of a protein during its synthesis by using information on the messenger RNA)

translocation ((genetics) an exchange of chromosome parts)

fertilized ovum; zygote ((genetics) the diploid cell resulting from the union of a haploid spermatozoon and ovum (including the organism that develops from that cell))

heteroploid ((genetics) an organism or cell having a chromosome number that is not an even multiple of the haploid chromosome number for that species)

haploid ((genetics) an organism or cell having only one complete set of chromosomes)
