What is a recessive easy definition?
: being or produced by a form of a gene whose effect can be hidden by a dominant gene and which can produce a noticeable effect only when two copies of the gene are present Blue eye color is a recessive trait. recessive.
What is recessive in a sentence?
Recessive gene-A type of gene that is not expressed as a trait unless inherited by both parents. Because Tay-Sachs is a recessive disorder, only people who receive two defective genes (one from the mother and one from the father) will actually have the disease.
What is recessive example?
Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous?). For example, the allele for blue eyes is recessive, therefore to have blue eyes you need to have two copies of the ‘blue eye’ allele.
What is dominant and recessive in simple words?
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
What is recessive mean in science?
Refers to a trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous genotypes.
What is recessive factor?
A recessive gene is a gene that can be masked by a dominant gene. In order to have a trait that is expressed by a recessive gene, such as blue eyes, you must get the gene for blue eyes from both of your parents. Its opposite is dominant and is always living in its shadow.

What is recessive gene Class 10?
A recessive gene is a gene whose effects are masked in the presence of a dominant gene. A recessive gene is only expressed when an organism has two recessive alleles for that gene.
What is difference between dominant and recessive?
What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
Which is recessive trait?
A recessive trait is a trait that is expressed when an organism has two recessive alleles, or forms of a gene. Dominant alleles mask the effects of recessive alleles, so a recessive trait is only expressed when an organism has two recessive alleles for a gene.
How do you use recessive in a sentence?
Recessive in a sentence. These are recessive genes. Usually one allele is dominant, the other recessive. He was so recessive that he could be in a room for a long time before anyone realized that he was there.
What is the meaning of the word recessive?
Definition of recessive (Entry 2 of 2) 1 : an organism possessing one or more recessive characters 2 : a recessive character or gene 1 : producing little or no phenotypic effect when occurring in heterozygous condition with a contrasting allele recessive genes
What are some recessive traits?
Common Recessive Traits. Common recessive traits include the lack of freckles and lack of dimples. The presence of freckles and dimples are both dominant traits. Common recessive traits with regard to facial features also include attached earlobes and thin lips.
What is the definition of recessive biology?
Recessive is defined as a gene with characteristics which are not as strong as those on a dominant gene. An example of a recessive is the gene for blue eyes.
