Purebreds have two identical copies of each gene for a particular trait. This is because they are homozygous for that trait, meaning they have two identical alleles.
When black dominates white in certain rat species, the genotype of the black rat would be homozygous dominant (BB), while the genotype of the white rat would be homozygous recessive (bb). When two hybrid black rats (Bb) are crossed, the possible genotypes of their offspring would be 25% homozygous dominant (BB), 50% hybrid (Bb), and 25% homozygous recessive (bb).
Purebred refers to an animal that comes from parents of the same breed, with a documented pedigree that traces its lineage back through multiple generations of that breed. This term is often used in reference to dogs, cats, and horses.
Barred Rock chickens are purebred. The word 'barred' is just a term for color. Barred means like white with gray stripes, for example. 'Rock' is the breed.

Purebred is only possible in Homozygous conditions such as AA or aa, and indvidual that is a hybrid (Aa) is not truebreeding and therefore is not purebred.
well that is hard and easy...... it would have to be purebred and hybrid. :p
A purebred organism is the offspring of two homozygous parents. A hybrid on the other hand, comes from two heterozygous parents, which is a cross between two species.
A purebred organism is the offspring of two homozygous parents, having either two dominant alleles, AA or two recessive alleles, aa. A hybrid is the offspring of two heterozygous parents, Aa.
The modern scientific term for "purebred" is homozygous.
Purebred
Yes, a genotype of TT or ff indicates a purebred individual for a specific trait. TT signifies homozygous dominant, while ff signifies homozygous recessive.
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.

C. heterozygous. Hybrid organisms are the result of crossing two different purebred parents, which leads to a mix of their genetic traits in the offspring. This results in the organism being heterozygous for many traits.
