If a pea plant has a recessive allele for green peas what will it produce?
A recessive allele means that the gene codes for an nonfunctional enzyme. If the pea plant has 2 recessive allele for the green pea gene, that means that the green pigment will not be deposited on the peas, as the enzyme is nonfunctional. The result would be yellow coloured peas.If the pea plant has one recessive and one dominant allele for the green pea pigment, then it will result in a half functional enzyme, which is sufficient for the green pigment to be deposited.
In pea plants green pod color is controlled by a dominant allele Yellow is controlled by a recessive allele Explain why a plant with yellow pods can never be a hybrid?
A plant with yellow pods can never be a hybrid because yellow pod color is controlled by a recessive allele, meaning the plant must inherit two copies of this allele to display the yellow color trait. Therefore, a plant with yellow pods necessarily has two copies of the recessive allele and cannot have a dominant allele for green pods.
If a pea plant is heterozygous for a particular character how can the alleles that control the character be described?
The alleles controlling the character in a heterozygous pea plant can be described as one dominant allele and one recessive allele. The dominant allele determines the plant's phenotype, while the recessive allele is masked in the presence of the dominant allele.
What is the genotype of a plant that produces green peas. Yellow peas are dominant?
The genotype of a plant producing green peas would be "yy," indicating that it carries two recessive alleles for yellow peas. The dominant allele for yellow peas is represented by "Y."
Why a plant with yellow pods can never be a hybrid?
Yellow pods are a recessive trait and for this type of trait to show in the phenotype, both alleles have to be recessive. If there was a recessive allele (yellow) and a dominant allele(green) as it shows in hybrid pods, then the dominant allele would be the one shown and the pod would be green.

If a pea plant has a allele for green peas it will produce?
green peas if it does not also have a dominant allele for yellow peas.
Mendel crossed a true green podded plant with a true yellow podded plant. All the offspring from this cross had green pods. Green is the?
Green is the dominant trait in this cross. Mendel's results demonstrate that when a dominant allele (for green pods) is present, it masks the effect of the recessive allele (for yellow pods), resulting in all offspring exhibiting the dominant phenotype. Thus, the true yellow podded plant contributes a recessive allele that does not express in the presence of the dominant green allele.

How did Mendel find out whether the recessive alleles were still present in the F1 plants?
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant

How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
The botanist could perform test crosses between the green-pod plant and a known homozygous recessive individual. If all offspring show the dominant green pod trait, the green-pod plant is likely homozygous. If the offspring display a mix of green and yellow pods, the green-pod plant is most likely heterozygous.
An allele is one of the alternative forms of a gene that governs a trait If a fern plant is heterozygous for a particular trait how can the alleles that control that trait be described?
If a fern plant is heterozygous for a particular trait, it means it carries two different alleles for that trait. The alleles can be described as one dominant allele and one recessive allele. The dominant allele will typically determine the physical expression of the trait, while the recessive allele will not be visibly expressed in the plant.
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.
If a heterozygous plant for seed color is crossed with a homozygous recessive plant what is the probability of each seed color being produced?
100%
