If the allele for yellow peas is Y the allele for the contrasting trait green peas is?
y
What else can I help you with?
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 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.
What happened when Mendel crossed a true breeding green seeded plant with a true breeding yellow seeded plant?
The seeds of the offspring are yellow because the allele for yellow seeds is dominant and the allele for green seeds is recessive. If you use a Punnett Square to show the way the possible gametes would pollinate, it would look something like this: Y Y Yy Yy Yy Yy y y Actually the small y's are supposed to be on the left side, but I can't figure out how to do it on this site. If there is one dominant allele, than that is the trait that shows up.
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.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What alleles are mask in complete dominance?
A recessive trait is a trait with two contrasting alleles. In some cases contrasting alleles for a trait are codominan, that is, both are expressed.
When Mendel bred green - pea plants and yellow - pea plants all the offspring had yellows means that?
When Mendel bred green pea plants with yellow pea plants and all the offspring were yellow, it indicated that the yellow trait is dominant over the green trait. This means that the yellow allele masks the expression of the green allele in the offspring. As a result, even though the green allele is present, it does not manifest in the phenotype of the plants. This observation was crucial in understanding the basic principles of inheritance.
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.
If Genotype of a G as dominate green and g for recessive yellow what would the heterozygous look like?
The heterozygous genotype would be Gg. This means the individual has one dominant green allele (G) and one recessive yellow allele (g). The dominant trait (green in this case) would be expressed in the phenotype of the individual.
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.
What is a contrasting trait?
pea has many sharply ditinct traits each trait has two clear alternative forms e.gseed shap has round or wrinkled phenotype plant hieght was long or short seed colour was yellow or green Mendel called them pair of contrasting trait

What is the genotype for round green peas?
The genotype for round green peas is typically represented as "RRyy," where "R" stands for the dominant allele for round shape and "y" represents the recessive allele for yellow color. In this case, the round shape is dominant over the wrinkled shape, while green color is recessive to yellow. Thus, the round green peas are homozygous for the round shape and homozygous recessive for the color trait.
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.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
