allele terms
relating to or denoting heritable characteristics which are controlled by genes that are expressed in offspring even when inherited from only one parent.
what is dominant
a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
gene
the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
crossing over
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
phenotype
the offspring of two plants or animals of different species or varieties, such as a mule
hybrid
relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent
Recessive
the study of heredity and the variation of inherited characteristics
genetics
the alleles of two (or more) different genes get sorted into gametes independently of one another
Law of Independent Assortment
containing more than two homologous sets of chromosomes
Polyploidy
having two identical alleles of a particular gene or genes.
homozyous
the genetic constitution of an individual organism
genotype
stating that during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent
the law of segregation
having two different alleles of a particular gene or genes
heterozyous
the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
