The possible genotypes are PpYY, PpYy, ppYY, and ppYy. The former two genotypes would result in plants with purple flowers and yellow peas, while the latter two genotypes would result in plants with white flowers with yellow peas, for a 1:1 ratio of each phenotype.
What is the genotypic ratio of pea plant?
That is, we expect a characteristic 9:3:3:1 phenotypic ratio of round-yellow : wrinkled-yellow : round-green : wrinkled-green pea seeds. That is, we expect a characteristic 1:2:1:2:4:2:1:2:1 ratio of the nine possible genotypes.
What are the 3 types of genotypes?
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
What would be the genotype for a heterozygous pea plant?
Hence the genotype of the heterozygous yellow seeded plant will be “Yy” and that for green seeded plant will be “yy” (as the recessive allele is expressed only in homozygous conditions).
What is the phenotype and genotype ratio of the pea plant?
The phenotypic ratio of Mendel’s monohybrid cross for height in pea plants in F2 generation was 3 : 1. The ratio indicates. No worries!
What is the genotypic ratio of F2 generation in pea plants?
1 : 1. Was this answer helpful?
What are 2 examples of genotypes?
Other examples of genotype include: Hair color. Height. Shoe size.
What is genotype in plants?
The genotype of a plant is a word used describes the genetic make – up of the plant. The context that it is used depends upon whether it is being used to describe the whole genome, the DNA sequence of individual genes or a collection of scores at different genetic markers.
What is AA AS and SS genotype?
Typically, there are five (5) distinct types of blood genotype. They are AA, AS, AC, SS, and SC. While the first 2 pairs (AA & AS) are normal, AC is rare and the latter two (SS, SC) are irregular and anomalous, commonly causing sickle cell disease.
How many genotypes are there?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes?
What is the genotype of pea plant with yellow pods?
Complete answer:
A pea plant with yellow round seeds is crossed with another plant with green wrinkled seeds. The genotype of yellow round seeds is YYRR and the genotype of green wrinkled seeds is yyrr.
What is the genotype for a pea plant heterozygous for round seeds?
Answer: Genotype of a plant pea heterozygous for round seeds and homozygous recessive for green seeds is (d) Rryy. Starting genotype of parents in a dihybrid cross would be (d) RrYy and RrYy.
What type of cross produces a 1 1 1 1 phenotypic ratio?
In the monohybrid cross, a testcross of a heterozygous individual resulted in a 1:1 ratio. With the dihybrid cross, you should expect a 1:1:1:1 ratio!
What is the genotype ratio of DD DD?
1:2:1
The Punnet square predicts a 1:2:1 genotype ratio for the DD,Dd and dd F2s.
What is the phenotype of a pea plant with a heterozygous genotype for height?
Tall. What is the phenotype of a pea plant that is heterozygous ( Tt )? It is also tall. The answer is yes, two different genotypes can result in the same phenotype.
What are the genotypes in F2 generation?
The F2 generation is more diverse, as the result of crossbreeding two heterozygous parents. The genotype distribution of the F2 generation is 25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive.
How many phenotypes and genotypes are possible in F2 generation?
Phenotypes-9 Genotypes-4.
How many types of gametes are formed from pea plant having genotype YYRR?
When the plant with Yyrr genotype is crossed with a plant with YYRR genotype, it produces three types of gametes, YR, Yr and yr.
What are the 4 types of genotypes?
There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.
Can AA get married to AA?
The compatible genotypes for marriage are; AA marries an AA — which is the best compatible, and that way, the couple save their future children the worry about genotype compatibility.
What does AA genotype mean?
If the dominant allele is labeled as “A” and the recessive allele, “a”, three different genotypes are possible: “AA”, “aa”, and “Aa”. The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive.
