Is a gender a dominant or recessive gean?
Purebreds can be recessive or dominant, depending on their genotype. A genotype for spots on a griaffe could be AA (purebred dominant), Aa (heterozygous dominant), or AA (purebred recessive)? AA and Aa would both show the dominant phenotype, but only AA and AA are purebreds.
How will you know if your plant is purebred and hybrid?
An organism which shows a dominant trait can be classified as pure breed or hybrid by test crossing it. In test cross, the organism is crossed with a recessive one. If the F1 progeny shows a dominance-recessiveness ratio of 1:1, it means that the organism was a hybrid. If the f1 progeny shows a ratio of 3:1, it means that the organism was a pure breed.
When a purebred plant with red flowers is crossed with a purebred plant that has white flowers what will be the expected result assuming that flower color in this plant is a co dominant trait?
That depends on which color is dominant. If red is dominant, then F1 will all be red heterozygous. If orange is dominant, then same applies.
How does hybridization happen?
Crossing one purebred plant (usually the same species) with another purebred plant will produce a hybrid.
What do the letters outside the punnett square stand for?
The letters on the outside of the Punnett square stand for the alleles of each parent. One parent's alleles are written across the top of the square, and the other parent's alleles are written along the left side of the square. The pairs of alleles inside the square represent all the possible genotypes for their offspring.
What is generation of all hybrids produced by crossing two pure organisms?
Mix the homozygous dominant with a homozygous recessive, and you will get a purebred!
What is the phenotype of a purebred recessive?
A recessive trait is known as the characteristic that is the outward expression of the gene. Recessive traits can be masked by dominant traits but are still present if the gene is present in the organism.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.

What do purebreeds conists of?
Purebreds is a term to describe organisms that contain a homozygous gene, whether dominant or recessive. Usually, this can be down through selective breeding which is practised in many industrial purposes, such as raising cattle. For example the gene for tallness is dominant, therefore represented by a T, while for shortness it is a recessive allele, which is represented by a t. A purebred for tallness can be either TT or tt, meaning purebred tall, or purebred short.
State Mendel's principle of dominance?
Only the dominant trait can be seen in an organism that is hybrid for a pair of contrasting traits
Is Recessive alleles the traits visible in the F1 generation of true-breeding organisms?
Only if the generations before were homozygous recessive as well. When doing the punnett square and you see there is a chance of having a heterozygous trait then that specie is not a purebred. The organism's offsprings must have the same physical traits.
Is a purebred pea plant small?
If the pea plant has the genetic to be small in the homozygous state, then it will be and conversely so. One of Mendel's experiments was to cross the purebred tall with the purebred small to see which trait was dominant. The allele for tallness is dominant in the pea plant,.

That depends on which color is dominant. If red is dominant, then F1 will all be red heterozygous. If orange is dominant, then same applies.
Is the long haired cat in the p generation a hybrid or purebred?
It's a purebred because it's offspring have the dominant trait in them.
