What does an alleles for a hybrid tall pea represent?
An allele for tall in a hybrid pea plant represents the gene that codes for the trait of tall height. In the case of a hybrid plant, there are two alleles for height, one inherited from each parent. If both alleles are for tall height (TT or Tt), the plant will exhibit the tall trait.
What happens in Mendel's experiments when a pea plant received two different alleles for the same trait?
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.
Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.
A purple-flowered plant that carries two different color traits such as purple and white is?
A heterozygous purple-flowered plant. This plant carries two different alleles for flower color – one for purple and one for white. When these two alleles are present together in a heterozygous individual, the dominant allele (purple) will typically be expressed.
What happened in Mendels experiments when a pea plant received two different alleles for the same traits?
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
Mendel determined that pea plants have two alleles that determine height Where do these alleles come from?
The two alleles for height in pea plants come from the parents of the pea plant. Each parent contributes one allele, which determines the height of the offspring.
Scientists call an organism that has two different alleles for a trait is what?
an organism that has two different alleles for a trait is heterozygous

What is the combination of alleles in purebred short pea plants?
Two alleles for tall stems.
In an experiment with pea plants, two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed?
They are fine; expected ratios might not be seen simply due to chance.
How do dominant and recessive alleles affect an offsprings phenotype?
The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.
What are two different alleleles for a trait called?
Different alleles for a trait are known as gene variants. For example, two different alleles for the gene that determines flower color in pea plants are purple (P) and white (p). When an individual has two different alleles for a trait, it is known as heterozygous.
Scientists compare two different plant species. In species A, the leaf color is controlled by two alleles. In species B, leaf color is controlled by five alleles. How will these two plants be different?
species B will have a wider range of phenotypes

A heterozygous purple-flowered plant. This plant carries two different alleles for flower color – one for purple and one for white. When these two alleles are present together in a heterozygous individual, the dominant allele (purple) will typically be expressed.
