A homozygous round pea plant is crossed with a heterozygous round pea plant?

take the pea plant that produces round seeds and self pollinate it. if in the f1 progeny or in the next filial generation all the plants produce round seeds then it is a homozygous plant and if some seeds are round whereas some are wrinkled then the plant is heterozygous.

∙ 13y agoround seeds are a dominant phenotype therefore a pea plant with round seeds could be either (R/r) or (R/R)
in order to test whether the plant is homozygous dominant or heterozygous cross the plant with a true-breeding wrinkly seeded plant, as wrinkly seeds are the recessive allele for this gene
therefore
(R/r) x (r/r) = 2/4 round seeds + 2/4 wrinkly seeds
(R/R) x (r/r) = 4/4 round seeds
depending on the results you achieve you'll known whether the plant is heterozygous or homozygous dominant

∙ 11y agoThe expected genotypic ratio is 2RR:2Rr. All of the offspring should have the round phenotype.

Suppose that in a pea plant round seeds are dominant over wrinkled seeds in the and ldquotexture and rdquo gene. If you were to take two plants heterozygous for the texture gene and cross them togethe?
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.
What was the probability that two heterozygous parents would have an offspring that produced round seeds?
25%
What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
If you put a couple of worms in your plant pot will it eat the plant?
Worms will not eat your plant but their circulation round the pot will disturb the rootball and cause the plant problems.r
What traits do not have complete dominance?
An example of incomplete dominance in humans is nose size. If you cross a person with a large nose, with someone with a small nose then the child may have a medium nose. This happens because neither trait dominates the other.
If a pea plant that is heterozygous for round yellow peas RrYy is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas RRYy how many different phenotypes are?

If a pea plant that is heterozygous for round yellow peas (RrYy) is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas (RRYy) how many different phenotypes are?

If a tall round seed plant is crossed with another tall round seed plant Tall dominant and both heterozygous?
The possible phenotypes are tall and round, tall and oval, short and round, and short and oval. Genes don't affect other genes during reproduction.
In pea plants are round or wrinkled seeds dominant?
In pea plants round seeds are dominant to wrinkled. So to have round seeds you either will have two dominant alleles (homozygous dominant) or one dominant and one recessive allele (heterozygous)
A pea plant with round seeds has the genotype Rr you cross this plant with a wrinkled seed plant genotype rr what is the probability that the offspring will have wrinkled seeds?
To figure this out, use a Punnet Square.First, set up a test cross, like this:Rr x rrThis shows what you are crossing. Now you can make a Punnet Square.R rr Rr rr There is a 50/50 chance that the corn plant will have thegenotype rr.r Rr rr
What are the chances of getting a square shape when 2 heterozygous square shapes are crossed?
75% 3/4 chance of it being square. 25% 1/4 change of it being round.
What is a round white pill with 315 on it?
Pill imprint 315 has been identified as Vytorin 10 mg / 80 mg.Vytorin is used in the treatment of high cholesterol; high cholesterol, familial heterozygous; high cholesterol, familial homozygous and belongs to the drug class antihyperlipidemic combinations.
What is probability that two heterozygous parents would have an offspring that produced round seeds?
It is a 75% chance that the seeds will be round.

What evidence is there that both the long and the round radishes are homozygous?
When the radish is heterzygous for shape The radish is oval.

What is a monohybrid cross and what is a dihybrid cross?
Monohybrid - A genetic cross made to examine the distribution of one specific set of alleles in the resulting offspringExample: tall peas x short peas or TT x ttDihybrid - Hybridization using two traits with two alleles each.Example: tall peas with round seeds x short peas with wrinkled seeds or TTRR x ttrr
