one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
A condition in which both alleles for a gene are fully expressed ( both are shown)
the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
the study of heredity
An organism's genetic makeup, or allele combinations.
An organism that has two different alleles for a gene or trait
A segment of DNA on a chromosome that codes for a specific trait
An organism that has two identical alleles for a trait or gene
An organism that has two different alleles for a trait; an organism that is heterozygous for a particular trait. the offspring of two plants or animals of different species or varieties, a thing made by combining two different elements; a mixture.
A pattern of inheritance in which two alleles, inherited from the parents, are neither dominant nor recessive. The resulting offspring have a phenotype that is a blending of the parental traits.
homologous chromosomes randomly goes to one side or the other.
An allele, or allel, is one of a number of alternative forms of the same gene or same genetic locus. It is the alternative form of a gene for a character producing different effects. Sometimes different alleles can result in different observable phenotypic traits, such as different pigmentation. ., three or more forms of a gene that code for a single trait.
An organism's physical appearance, or visible traits.
Traits controlled by two or more genes
Principle of Dominance
states that some alleles are dominant and others are recessive. The idea that states that one factor (gene) in a pair may mask the other (recessive) gene.
A number that describes how likely it is that an event will occur
A chart that shows all the possible combinations of alleles that can result from a genetic cross
(genetics) the separation of paired alleles during meiosis so that members of each pair of alleles appear in different gametes
A characteristic that an organism can pass on to its offspring through its genes.
A fertilized egg or a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
Any chromosome that is not a sex chromosome
he failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division, usually resulting in an abnormal distribution of chromosomes in the daughter nuclei.
A diagram that shows the occurrence of a genetic trait in several generations of a family, A diagram that shows the occurrence of a genetic trait in several generations of a family
One of the 23 pairs of chromosomes in the human, contains genes that will determine the sex of the individual
gene located on the X or Y chromosome
