Answer: 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 are the three possible genotypes for flower color in pea plants?
So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
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 genotypes of 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 the genotype of a pea plant that’s homozygous?
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.
Genotype and Phenotype.
| Genotype | Definition | Example |
|---|---|---|
| Homozygous dominant | Two dominant alleles | TT |
| Homozygous recessive | Two recessive alleles | tt |
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 are 3 examples of genotype?
Three examples of genotypes are: Homozygous dominant – An organism has two dominant alleles for a gene. Heterozygous – An organism has two different alleles for a gene. Homozygous recessive – An organism has two recessive alleles for a gene.
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!
How do you write a genotype?
The genotype is often written as YY or yy, for which each letter represents one of the two alleles in the genotype. The dominant allele is capitalized and the recessive allele is lower case.
How do you determine a genotype?
To determine a genotype, you can use a Punnett square. If you are working in a more advanced laboratory, you can use analytical methods such as PCR analysis and nucleic acid hybridization to determine what genotypes are present.
Which is the genotype of the sweet pea?
The image shows a white sweet pea that is labeled with its two alleles for petal color. What can you surmise from the labeled image? The genotype is heterozygous.
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.
What are the 5 types of genotype?
A blood genotype indicates the genetic makeup of an individual’s blood in its entirety. Typically, there are five (5) distinct types of blood genotype. They are AA, AS, AC, SS, and SC.
What is the genotype of a heterozygous pea plant?
Inside the 4 boxes are the possible genotypes (with respect to plant height) of the offspring from these parent pea plants. In this case, the only possible genotype is Tt (heterozygous).
What is the genotype of a pea plant that’s homozygous for height?
genotype TT
a homozygous tall pea plant will have the genotype TT. A homozygous short pea plant will have the genotype tt.
What is the genotype for a heterozygous pea plant for round and green seeds?
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 AA and AA genotype?
Genotype AA is the universally compatible genotype that is, regardless of who they partner up with, there is no possibility of them birthing a child with sickle cell disease. Here are the compatible and incompatible genotypes: AA + AA = compatible. AA + AS = compatible. AA + SS = compatible.
What are the type of genotypes?
The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes? A blood test is used to determine whether the A and/or B characteristics are present in a blood sample.
What genotype means?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes.
Is aa an example of genotype?
Types of Genotype
The genotypes in humans are AA, AS, AC, SS. They refer to the hemoglobin gene constituents on the red blood cells.
What is the common genotype?
Genotypes 1, 2, and 3 are more common and genotypes 4, 5, and 6 are known to be localized to limited regions [169,170]. In the distribution of geographical area, genotype 1a is common in North America and Northern Europe, and 1b is common in Far East Asia and Europe [132].
