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.
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 "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 used to pea plants to discover gene inheritance.
No, a gene is larger than an allele. Genes are segments of DNA that code for specific traits, while alleles are different versions of the same gene that can result in different phenotypic expressions.
According to Mendel's principle of segregation, recessive genes disappear in the F1 generation of pea plants when they are crossed with dominant genes. This is because the dominant gene masks the presence of the recessive gene in the phenotype of the offspring.
It was discovered by Gregor Mendel with his experiment on pea plants.
Smooth yellow pea plants and wrinkly green peas.
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.
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.
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.
the tall trait was controlled by a dominant factor.
two tall genes or one tall gene and one short gene
Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
cuz hez weerd
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's laws of inheritance, recessive genes may appear to disappear in the F1 generation of pea plants when crossed with dominant genes. In the F1 generation, only the dominant trait is expressed, masking the recessive trait. However, the recessive gene is not lost but can reappear in subsequent generations.
