The branch of biology that studies heredity and variation in organisms

Classified under:

Nouns denoting cognitive processes and contents

Synonyms:

genetic science; genetics

Hypernyms ("genetics" is a kind of...):

biological science; biology (the science that studies living organisms)

Domain member category:

filial (designating the generation or the sequence of generations following the parental generation)

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)

translation ((genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm)

transduction ((genetics) the process of transfering genetic material from one cell to another by a plasmid or bacteriophage)

transcription ((genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA; the process whereby a base sequence of messenger RNA is synthesized on a template of complementary DNA)

segregation ((genetics) the separation of paired alleles during meiosis so that members of each pair of alleles appear in different gametes)

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)

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

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

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

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

parental (designating the generation of organisms from which hybrid offspring are produced)

multivalent (used of the association of three or more homologous chromosomes during the first division of meiosis)

bivalent; double (used of homologous chromosomes associated in pairs in synapsis)

univalent (used of a chromosome that is not paired or united with its homologous chromosome during synapsis)

polygenic (of or relating to an inheritable character that is controlled by several genes at once; of or related to or determined by polygenes)

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

heterozygous (having dissimilar alleles at corresponding chromosomal loci)

homozygous (having identical alleles at corresponding chromosomal loci)

triploid (of a cell or organism having three complete sets of chromosomes)

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)

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)

transposition ((genetics) a kind of mutation in which a chromosomal segment is transfered to a new position on the same or another chromosome)

hereditary pattern; inheritance ((genetics) attributes acquired via biological heredity from the parents)

unit character ((genetics) a character inherited on an all-or-none basis and dependent on the presence of a single gene)

character ((genetics) an attribute (structural or functional) that is determined by a gene or group of genes)

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

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)

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

amphidiploid ((genetics) an organism or cell having a diploid set of chromosomes from each parent)

carrier ((genetics) an organism that possesses a recessive gene whose effect is masked by a dominant allele; the associated trait is not apparent but can be passed on to offspring)

chromosome mapping; mapping ((genetics) the process of locating genes on a chromosome)

cross; crossbreeding; crossing; hybridisation; hybridization; hybridizing; interbreeding ((genetics) the act of mixing different species or varieties of animals or plants and thus to produce hybrids)

gene linkage; linkage ((genetics) traits that tend to be inherited together as a consequence of an association between their genes; all of the genes of a given chromosome are linked (where one goes they all go))

cistron; factor; gene ((genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity)

inversion ((genetics) a kind of mutation in which the order of the genes in a section of a chromosome is reversed)

deletion ((genetics) the loss or absence of one or more nucleotides from a chromosome)

chromosomal mutation; genetic mutation; mutation ((genetics) any event that changes genetic structure; any alteration in the inherited nucleic acid sequence of the genotype of an organism)

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

Mendel's law ((genetics) one of two principles of heredity formulated by Gregor Mendel on the basis of his experiments with plants; the principles were limited and modified by subsequent genetic research)

sex chromosome ((genetics) a chromosome that determines the sex of an individual)

XYY ((genetics) abnormal complement of sex hormones in a male who has two Y chromosomes)

XY ((genetics) normal complement of sex hormones in a male)

XXY ((genetics) abnormal complement of sex hormones in a male resulting in Klinefelter's syndrome)
