What is phenotype and example?

In humans, phenotype examples include earwax type, height, blood type, eye color, freckles, and hair color. And phenotypes aren't just physical traits. Behavior is also considered a phenotype. An example of inherited behavior is provided by Border Collies, a dog breed that was bred to herd sheep.

What is a simple definition of phenotype?

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 3 examples of phenotype?

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.

What is a genotype and phenotype?

The genotype is a set of genes in DNA responsible for unique trait or characteristics while the phenotype is the physical appearance or characteristic of an organism.

How do you determine a phenotype?

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What's a genotype example?

Genotype examples

A gene encodes eye color. In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father. The brown allele is dominant (B), and the blue allele is recessive (b).

What is AA and AS 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. AC is rare whereas AS and AC are abnormal.

Can an AS marry an AS?

Also, when an AA marries an AS, the couple end up with AA and AS children which is good, but sometimes if unlucky, all the kids can be AS, which limits their choice of partner.

One study involving 372 children at the University of Uyo Teaching Hospital found that “children with genotype AA (92.3%) were more susceptible to malaria parasite than AS (5.1%) and SS (2.6%)”.

What is the best blood group and genotype?

What Blood Genotypes Are Compatible? The AA genotype has the best compatibility ratio. An individual with the AA genotype can choose a life partner from virtually all other genotype categories with an extremely minimal possibility of sickle-celled offspring.

Which blood group should not marry?

This is mediated by the antigen-antibodies reaction. Transfer of maternal antibodies across the placenta occurs. This happens when Rh +ve man marries Rh-ve lady. So Rh +ve man should try to avoid marrying Rh-ve lady.

What happens if husband and wife have same blood group?

The blood group of the child's blood is also positive if the husband's blood group is positive. If the husband's blood group is positive and the blood group of the wife is negative, then the female contains a fatty or fetus of the positive group.

What happens if husband and wife have same blood group A?

There are no disadvantages for married couples having same blood group. If you are A+ and your husband is A+ also then according to genetic principles the baby born will have the same blood group as A+ and thus no complications shall arise out of it.

What is the healthiest blood type?

Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.

What blood type is the strongest?

O− blood, also called "universal donor," is perhaps the most valuable blood in the world because it can be transfused to nearly any blood type (except when the person has some rare antigen outside of the main ones).

What is the rarest blood type?

type AB

In the U.S., the blood type AB, Rh negative is considered the rarest, while O positive is most common.

Why is Rh negative so rare?

Only people with at least one Rh-negative factors will have a negative blood type, which is why the occurrence of Rh-negative blood is less common than Rh-positive blood.

What blood type is A royal blood?

O: Blood group O means that both antigens A and B are absent from the RBC surface. Blood group O can be O- (O negative) or O+ (O positive) depending upon the absence or presence of the Rh antigen on the surface of the RBCs.
...
Table 1. Blood Types.
A negative (A-)A positive (A+)
O negative (O-)O positive (O+)

Why is O negative so rare?

Only 7% of the population have O negative blood. Due to the its versatility for transfusions, it is in high demand. In an emergency, it is the blood product of choice. For example, just one car accident victim can require up to 100 units of O neg.
