The physical appearance of an organism based on traits. Genotype. Phenotype.

What is the definition of genotype Quizizz?

What is the definition of genotype? The physical expression of a trait. The genetic combination of alleles.

Which of the following is a 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.

Which trait will always be expressed if present because it will mask the expression of others?

​Codominance

Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.

Which of the following is the correct definition for a genotype *?

Genotype: The genetic constitution (genome) of a cell, an individual, or an organism. The genotype is distinct from the expressed features, or phenotype, of the cell, individual, or organism. The genotype of a person is that person’s genetic makeup. It can pertain to all genes or to a specific gene.

What is example of phenotype?

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.

What is the phenotype of RR?

The allele that produces red flower color (R) is not completely expressed over the allele that produces white flower color (r). The result in the heterozygous genotype (Rr) is a phenotype that is a mixture of red and white, or pink.

What’s my phenotype and genotype?

An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. A change in the environment also can affect the phenotype. …

What is difference between genotype and phenotype?

The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics. Whereas the phenotype is the physical appearance or characteristic of the organism. … Such traits are hair color or type, eye color body shape, and height, and many such more.

Who is considered as the father of genetics?

Gregor Mendel: the ‘father of genetics’ In the 19th century, it was commonly believed that an organism’s traits were passed on to offspring in a blend of characteristics ‘donated’ by each parent.

What does the notation TT mean to geneticists?

An organism can be either homozygous dominant (TT) or homozygous recessive (tt). If an organism has two different alleles (Tt) for a certain gene, it is known as heterozygous (hetero means different).

Why do blood type AB is called codominant with each other?

AB blood type is codominant because the red blood cells have the products of both the A and the B alleles of the ABO gene.

Can As marry as?

However, AS and AS should not marry because there is every chance of having a child with Sickle Cell Disease, while AS and SS shouldn’t think of marrying. And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

What is an allele that can mask another allele?

When one of the alleles of a heterozygous pair masks the presence of another, recessive allele, it is known as a dominant allele.
