What are the possible phenotypes?
Table 4-5. Correlation of ABO phenotypes and genotypes.
| Phenotype | Possible Genotype |
|---|---|
| A | AA or AO |
| B | BB or BO |
| AB | AB |
| O | OO |
What are the 3 phenotypes?
If the only alleles for hair texture were straight and curly, there would be three phenotypes: straight, curly, and wavy. However, you asked for something a little different. You wanted three phenotypes that are all equally represented in the population.
What are the 5 phenotypes?
Phenotype Examples
- Eye color.
- Hair color.
- Height.
- Sound of your voice.
- Certain types of disease.
- Size of a bird’s beak.
- Length of a fox’s tail.
- Color of the stripes on a cat.
What is the dominant trait for dimples?
Are facial dimples determined by genetics? Dimples—indentations on the cheeks—tend to occur in families, and this trait is assumed to be inherited. Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples.
What is the possible genotypes and phenotypes?
Genotype & Phenotype. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa.
What are phenotypes and genotypes?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What are phenotypes examples?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. Examples of phenotypes include height, wing length, and hair color.
How many phenotypes are there?
There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.
What is the phenotype for DD?
Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS (has two different alleles for a specific gene). Although Susan has both the allele “D” to make dimples and the allele “d” in her genotype, her phenotype is the presence of dimples….
| t | t | |
|---|---|---|
| t | tt (short) | tt (short) |
Is TT a phenotype or genotype?
Genotype and Phenotype
| Genotype | Definition | Example |
|---|---|---|
| Homozygous | Two of the same allele | TT or tt |
| Heterozygous | One dominant allele and one recessive allele | Tt |
| Homozygous dominant | Two dominant alleles | TT |
| Homozygous recessive | Two recessive alleles | tt |
Which is the dominant trait of a dimple?
Dominance and Dimples. A dimple is a dominant trait. Say John, who has two dominant dimple genes (DD), and Jane, who has two recessive dimple genes (dd), have a baby named Alice. Alice will receive one allele from each parent.
Are there two different forms of the dimples gene?
The dimples GENEis that portion (DNA sequence) of a specific chromosome that controls the expression of the Dimples trait. But there appears to be two different phenotypes in our scenario, as there are two different ALLELES(alternative forms of one gene).
What is the genotype for dimples in Alice in Wonderland?
Alice will receive one allele from each parent. Based on her parents’ genetic information, she must receive one dominant allele from John and one recessive allele from Jane, so Alice’s dimple alleles will be represented by Dd, meaning she will have dimples. Say Alice grows up and has children with Alan.
How does the body tell if you have dimples?
Chromosomes carry their genes in the same place, but these genes have different versions, called alleles. Some alleles are dominant and some are recessive. In the case of dimples, one allele can tell the body to have dimples, while another may say “no” to the genetic trait.
