You perform a test cross on a tall pea plant half the offspring are short what conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous
What genes does a homozygous short pea plant always have?
Recessive genes
What is the probability of producing a tall pea plant from a genetics cross between two hybrid tall pea plants?
50%
If a crosss between a tall pea plant and a short pea plant produces all tall ofspring then tallness is mostly likely?
Yes, that is called a dominant trait.
In pea plants tall (T) plants are dominant over short (t) plants. If a heterozygous (Tt) pea plant is crossed with a homozygous dominant (TT) pea plant all of the resulting pea plants should be tall (?
Dominant Allele
A pea plant with two tall genes is called?
Heterozygous
What is the difference between a Pure tall plant and hybrid tall plant?
Pure TraitsPure traits can be either recessive or dominant. Pure traits may have two dominant genes or two recessive genes. For example, a pea plant may have two genes for tallness, which is dominant trait in pea plants. This plant is homozygous plant with a pure dominant trait for tallness. All of the offspring from this plant will be tall. A pea plant with two genes for shortness is also a pure organism. However, shortness in pea plants is a recessive trait. This plant is a homozygous plant with a pure recessive trait for height. The offspring from this plant will be short if it pollinates with another plant that has two genes for shortness. If this plant pollinates with a tall pea plant, the tall dominant gene will mask or cover up the recessive gene for shortness. Both plants are homozygous or pure plants; one is a pure dominant pea plant, the other is a pure recessive pea plant.Hybrid TraitOrganisms 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. The offspring from a pure tall pea plant, cross-pollinated with a pure short pea plant, will result in a heterozygous plant for tallness. No organism has all dominant or all recessive genes. An organism may be pure in certain traits and hybrid others. Remember, that a dominant trait in one kind of organism may be a recessive trait in another organism.

You perform a test cross on a tall pea plant half the offspring are short what conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous
What genotype is a tall pea plant?
A tall looking pea plant can have a genotype of Tt or TT.
What genes does a homozygous short pea plant always have?
Recessive genes
What combinations of genes could tall pea plants have?
two tall genes or one tall gene and one short gene
A testcross on a tall pea plant produces only tall offspring. What is the genotype of the tall pea plant?
Tt
This Punnett square sHow is the results of a cross between a tall pea plant and a short pea plant If tall is the dominant form of the trait what is the genotype of the tall pea plant?
TT or Tt
What perform a testcross on a tall pea plant. Half the offspring are short. What conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous!
Can a short pea plant ever be a hybrid?
No, the short pea trait is recessive and the tall pea plant trait is dominant. This means that if the plant is a hybrid, it has to be a tall pea plant. The dominant traits "mask" the recessive traits. The plant take one trait from their mom and one from their dad. If either the mom or the dad was not a tall, not hybrid pea plant then their kids would have to be tall be cause they would have one dominant, tall trait
Can a short pea plant ever be a hybrid for the trait of stem height?
yea for sizzle
