An organism with a hybrid trait may contribute either a dominant or recessive allele. In this way, an organism’s offspring can be phenotypically different from its parents. For example, if both parents have a particular hybrid trait, the offspring can have a homozygous pairing of recessive alleles in that trait.
Is homozygous purebred or hybrid?
Purebred – Also called HOMOZYGOUS and consists of gene pairs with genes that are the SAME. Hybrid – Also called HETEROZYGOUS and consists of gene pairs that are DIFFERENT. Genotype is the actual GENE makeup represented by LETTERS.
Are hybrids heterozygous?
A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.
Is hybrid dominant or recessive?
Organisms that have two unlike genes for a certain trait are called hybrid. A pea plant with one recessive gene for shortness and one dominant gene for tallness is a hybrid for that trait. A hybrid is called heterozygous, as it has two different alleles.

What genotypes are hybrids?
AA/bb and Aa/Bb. No, AA/bb is a pure-bred genotype, but Aa/Bb is a hybrid genotype. The possible genotypes of the pure-bred plants are AA/bb and aa/BB. Shull found that when he crossed the two pure-breds, the offspring grew much better.
What’s the difference between pure and hybrid?
In the simplest possible terms, purebreds are the offspring that result from mating between genetically similar parents while hybrids are the offspring that are the result of mating between two genetically dissimilar parents.
What is the difference between heterozygous and homozygous?
Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.
Is F1 generation homozygous?
One parent is homozygous for one allele, and the other parent is homozygous for the other allele. The offspring make up the first filial (F1) generation. Every member of the F1 generation is heterozygous and the phenotype of the F1 generation expresses the dominant trait.
How will you identify that F1 hybrid is homozygous or heterozygous explain it with suitable example?
For example, a pea plant having purple flowers (F1 hybrid with unknown genotype) is crossed with a pea plant with white flowers (recessive). If all flowers produced are purple, we can conclude that plant is pure or homozygous and if we get purple and white flowers in a 1:1 ratio, conclude that plant is heterozygous.
What is a hybrid for a given trait?
A hybrid trait is also known as a heterozygous trait, and is the pairing of a dominant and recessive allele. … Therefore, an organism that is heterozygous for a trait will have the same outward manifestation of that trait as an organism that has a dominant homozygous trait.
