What kind of gene disappear in F1 pea plants?
Recessive
When Mendel crossed pea plants that differed in two characteristics such as flower color and plant height what happended?
He tested seed color and shape at the same time.
When Mendel crossed a pure breeding tall pea plant with a pure breeding short pea plant all of the resulting plants were tall In this case the tall gene was and the short gene was?
This means that the tall pea plant had a double dominant height gene (each gene has 2 parts, one from each "parent"). The short pea plant had a double recessive gene making it short. When the two plants bread, the dominant gene always is the one that shows up, so the plant was tall.
Is an allele bigger then a gene?
An allele is a gene. It is one form of a gene. For example, height in pea plants is controlled by one gene with two forms. A pea plant can be tall or short. There is a short allele and a tall allele for the gene governing height.
Explain how dominant and recessive alleles for the trait of stem height determine whether a pea plant will be tall or short?
Depends, Wether The Type Of Seeds or if the dominanat gene/ trait is tall then the pea plant is going to be tall because if the recessive gene is small the dominant one takes over it so tall pea plants will grow
What kind of gene disappear in F1 pea plants?
Recessive
What are the possible genotypes of pea plants?
Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.

When mendel crossed a strain of tall pea plants with a strain of short pea plants he observed that all the f1 generation were tall this suggest that?
the tall trait was controlled by a dominant factor.
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.

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.

What is the recessive color of a pea plants seed coat?
In most pea plants it is yellow, but there are probably other colors in rarer plants.
If a pea plant is heterozygous for a particular character how can the alleles that control the character be described?
One is dominant gene and one recessive gene.
What happen in Mendel experiment when a pea plant received two different alleles for the same trait?
He did an experiment with a tall pea plant and a small pea plant. He then went through 2 generations of breeding of these plants and noticed 3 distinct different types of plants. One type was really short, the other was average height, and the final was Tall.He combined 2 medium sized plants with each other (Tt) and (Tt).*T = Tall gene.*t = shortness gene.Put that into you Punnett square and you will get these answers:The small plant had a recessive gene (tt).The medium sized plant had the average set of genes (Tt).The tall plant also had a recessive gene (TT).The results were:1 Small Plant, 2 Medium Plants, and 1 Large Plant.The recessive allele was hidden by the dominant alleleThe recessive allele was hidden by the dominant allele.the recessive allele was hidden by the dominant allele. (novanet)The recessive allele was hidden by the dominant allele.Novanet Swagnovanet:The recessive allele was hidden by the dominant allele!
