∙ 11y agoAll F1 offspring produced will be heterozygous for green and yellow alleles and produce yellow peas indicating that yellow color is dominant. Therefore the F1 plants will all produce yellow seeds.

∙ 9y agoIf yellow is the dominant allele, then the heterozygous plants would have yellow peas. Heterozygous individuals have a dominant phenotype.

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 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 is a contrasting form of a hereditary characteristic called?
I had this question on a test as a multiple choice so I know the answer is either genotype, heredity, allele or gene if that helps.
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.
What is an organism that is heterozygous for two traits?
An organism that is heterozygous for two traits means that it contains both the dominant allele and the recessive allele for both of the traits in question. For example, take a plant that produces peas. The gene that produces yellow seeds (denoted Y) is dominant, the gene for green seeds (y) is recessive. The gene that produces round seeds is dominant (R), the gene for wrinkled seeds (r) is recessive. So if this organism was heterozygous for both traits its genotype would be: Yy/ Rr Which means it has the allele for yellow seeds and the allele for green seeds (trait one), and also has the allele for round seeds and the allele for wrinkled seeds (trait two). Its phenotype (the traits it displays) will be yellow round seeds, as these are the dominant traits.

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

An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
What is member of a gene pair that determines a specific trait is?
an allele

How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
What allele does affect the trait in a heterozygote?
The recessive allele.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
