What else can I help you with?
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 in the pea plants the tall-stem and short-stem allele are different forms of the same?
Yes, in pea plants the tall-stem and short-stem alleles are different forms of the same gene that controls stem length. These different forms, or alleles, result in the observable variations in stem height seen in pea plants.
Suppose that in a pea plant round seeds are dominant over wrinkled seeds in the and ldquotexture and rdquo gene. If you were to take two plants heterozygous for the texture gene and cross them togethe?
Suppose that, in a pea plant, round seeds are dominant over wrinkled seeds in the "texture" gene. If you were to take two plants heterozygous for the texture gene and cross them together to make eight new plants, how many of those plants should express the smooth phenotype? Use a Punnett's Square to determine the results.
Gregor Mendel is studied because he what?
Gregor Mendel is studied because he used to pea plants to discover gene inheritance.
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.
According to Mendel what kind of genes disappear in F1 pea plants?
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.
Who discovered the gene?
It was discovered by Gregor Mendel with his experiment on pea plants.
What kind of pea plants did Mendel use?
Smooth yellow pea plants and wrinkly green peas.
Is an allele larger than 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.

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 are the possible genotypes of pea plants?
Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
What combinations of genes could tall pea plants have?
two tall genes or one tall gene and one short gene
Why did mendel not observe gene linkage during his expirements with pea plants?
cuz hez weerd
If homozygous tall pea plant and a homozygous short pea plant are crossed?
The resulting offspring will be 25% tall homozygous, 25% short homozygous, or 50% heterozygous. Depending on the gene, the heterozygous will either have codominance, incomplete dominance, normal dominance depending on which gene is dominantly expressed.
According to mendel what genes disappear in f1 pea plants?
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both a dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.
