A plant with two recessive genes for height is crossed with a plant with one dominant and one recessive gene for height What genes will their offspring have?

hh X Hh
You get two recessives; hh and hh
and two heterozygous plants; Hh and Hh

If a homozygous tall and short pea plant are crossed will the offspring be of medium height?
Not if either trait is dominant. Let us say tall is dominant ( I think it is ) and short is recessive. T = tall, and s = short. TT X ss will give heterozygous tall plants. Ts
What are three types of genotypes that exist for pea plant height?
Homozygous dominant Homozygous recessive and Heterozygous
When mendel crossed true breeding tall plants with true breeding short plants all the offspring were tall because?
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
What happens to A trait controlled by a dominant gene?
yes, if two Bb parents have kids, there is a 3:1 ratio that their children will show a dominant trait (BB Bb Bb bb). For multiple alleles (3 or more) it gets a little more complicated. Some traits, like height, have 1000's of genes affecting them. Consult your biology teacher for more information.Yes. Because to have a dominant trait you can have two dominant alleles or just one dominant and one recessive (because a dominant allele negates the effect of a recessive allele.) To get a recessive trait it takes two recessive alleles as oppose to a dominant trait where it takes only 1 to have a dominant trait. Therefore Dominant traits are more common.
What do you call an organism that possesses two dominant or two recessive genes fir a single trait?
I think you are referring to the term homozygous. This term applies not to the entire organism but is typically used with regard to one trait. For example, homozygous tall or homozygous dwarf when referring to height in peas. The term heterozygous refers to having one dominant and one recessive gene, or at least to having two different forms of the gene.
What is the height of the f1 plant if the tall plant AABBCC is crossed with a base height plant aabbcc?
In such a cross, the F1 plants will always be tall, because that is the dominant allele. In the cross described, a homozygous dominant plant was crossed with a homozygous recessive plant; a cross that produces 100% heterozygous offspring. (AaBbCc)
If a homozygous tall and short pea plant are crossed will the offspring be of medium height?
Not if either trait is dominant. Let us say tall is dominant ( I think it is ) and short is recessive. T = tall, and s = short. TT X ss will give heterozygous tall plants. Ts
Two organisms each with the genotypes Tt Gg mate The chance of producing an offspring that has the dominant phenotype for height T and the recessive phenotype for color g is?
If two organisms, each with genotypes tt+gg mate. What is the chance of producing and offspring that has the dominant phenotype for height (t) and the recessive phenotype for color (g)
What did Mendel call the observed trait and the trait that seemed to disappear?
he called the observed traits dominant and the disapear traits recessive.
How dominant or recessive alleles for the trait of stem height determine whether a pea plant will be tall or short?
The dominant trait for height in a pea plant is tall (TT or Tt). The only instance in which a pea plant will be short is if it carries both recessive alleles (tt).
What are three types of genotypes that exist for pea plant height?
Homozygous dominant Homozygous recessive and Heterozygous
When mendel crossed true breeding tall plants with true breeding short plants all the offspring were tall because?
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
What are the genotypes of a dominant tall pea plant to short pea plants?
Really, there is no set letter for any allele. It is common, however, to use the first letter of the dominant allele. Since tall height is dominant over short height in pea plants, then the allele for short would be the t (a lowercase t).
What does the notation Tt mean to geneticsts?
That this person is medium height, because the 1st T is the dominant one but the second t is recessive making the person medium height. :) ^is wrong one allies is dominant
What statement would mostly clearly refer to a persons genotype?
Bill is recessive for height and dominant for hair color.
What is the difference between a pure tall plant and a 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.
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.
