Hybrid (biology)update 1 Hybrid generally refers to any offspring resulting from the breeding of two genetically distinct individuals, which usually will result in a high degree of heterozygosity, though hybrid and heterozygous are not, strictly speaking, synonymous. Extremely rare interfamilial hybrids have been known to occur (such as the guineafowl hybrids). 2  No interordinal (between different orders) animal hybrids are known. 3  The third type of hybrid consists of crosses between populations, breeds or cultivars within a single species.

Leafly Glossary of Cannabis Terms Hybrid. Hybrid refers to a plant that is genetically a cross between one or more separate strains of cannabis. Hybrids can happen unintentionally, but they are usually bred specifically to combine desired traits of the original plants. Most marijuana on the market today is some form of hybrid.

Allele Allelic variation at a locus is measurable as the number of alleles (polymorphism) present, or the proportion of heterozygotes in the population. A null allele is a gene variant that lacks the gene's normal function because it either is not expressed, or the expressed protein is inactive.

- Definition. noun, plural: alleles. (genetics). One member of a pair (or any of the series) of genes occupying a specific spot on a chromosome (called locus) that controls the same trait.

- An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where it may appear as F1 crossbreed. The term is sometimes written with a subscript, as F1 hybrid.

Heterozygous Traits An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome.These DNA codings determine distinct traits that can be passed on from parents to offspring.ince organisms have two alleles for each trait, when the alleles of a pair are heterozygous, the dominant allele trait is expressed and the recessive allele trait is masked. Seeds with the genetic makeup of (YY) or (Yy) are yellow, while seeds that are (yy) are green. More Genetics Information: 1  Chromosomes and Sex.

Definitions &Translations Heterosis, hybrid vigor, or outbreeding enhancement, is the improved or increased function of any biological quality in a hybrid offspring. The adjective derived from heterosis is heterotic.

- (For example, one phenotype of a pea plant is having purple flowers.) A dihybrid cross is a cross between two individuals that are both heterozygous for two different genes. A hybrid is just the offspring produced when two genetically different parents are crossed.ven though the parents of a dihybrid cross have the same genotype and phenotype, their offspring could show any one of 9 different genotypes and 4 different phenotypes. The phenotypic ratio of offspring produced from a dihybrid cross is 9:3:3:1. To unlock this lesson you must be a Study.com Member.

allele allele. An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Biology Genetics (Theoretical Genetics) Heterozygous: having two different alleles of a gene. Carrier: an individual that has one copy of a recessive allele that causes a genetic disease in individuals that are homozygous for this allele. Test cross: testing a suspected heterozygote by crossing it with a known homozygous recessive.

BIOLOGY 121 inheritance Hybrid sterility is what results when individuals from two. different species are able to mate but their offspring is infertile, meaning that their. offspring are not able to reproduce. Because this occurs after the formation of the. zygote, this is a postzygotic isolating mechanism, not a prezygotic mechanism.

Heredity This is an organism that has two identical alleles for the same genetic trait. Hybrid This is the offspring of a genetic cross between parents with different traits. Incomplete Dominance This is a trait that is a blend of the dominant and recessive gene; inheritance pattern where the phenotype of a heterozygote is intermediate between those of the two homozygotes; neither allele of the pair is dominant but combine and display a new trait.

- By Regina Bailey. Definition: Heterozygous refers to having two different alleles for a single trait. Related Terms: Allele, Genes, Homozygous. Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r).hen the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive.

Hybrid Hybrid, offspring of parents that differ in genetically determined traits. The parents may be of different species, genera, or (rarely) families. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species.

Hybrid (golf) A hybrid is a type of club used in the sport of golf with a design borrowing from both irons and woods while differing from both.he name  hybrid  comes from genetics to denote a mixture of two different species with desirable characteristics of both, and the term here has been generalized, combining the familiar swing mechanics of an iron with the more forgiving nature and better distance of a wood.

Backcross Breeding 1 - Basic Gene Inheritance Homozygous plants have two identical copies of a single gene. Heterozygous plants have two copies of a single gene, but those copies are alleles, or different versions of that gene. Example of alleles controlling a trait for susceptibility to a lesion-causing disease.

- 1 The cross between two different homozygous lines produces an F1 hybrid that is heterozygous; having two alleles, one contributed by each parent and typically one is dominant and the other recessive. 2  Typically, the F1 generation is also phenotypically homogeneous, producing offspring that are all similar to each other. Extremely rare interfamilial hybrids have been known to occur (such as the guineafowl hybrids). 2  No interordinal (between different orders) animal hybrids are known. 3  The third type of hybrid consists of crosses between populations, breeds or cultivars within a single species.

Allele: A Genetics Definition Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked.
