A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. In a dominant/recessive relationship between two alleles, the recessive allele’s effects are masked by the more dramatic effects of the dominant allele.
What does recessive allele mean?
Recessive refers to a type of allele which will not be manifested in an individual unless both of the individual’s copies of that gene have that particular genotype.
What is recessive in simple words?
: 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 and dominant allele?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
What is a recessive allele quizlet?
A recessive allele is an allele that is masked when a dominant allele is present. … A Punnett square is a chart that shows all the possible combinations of alleles that can result from a genetic cross.
What is recessive gene in biology?
A recessive gene or allele is one in which the effect is not tangible, or is masked by the effects of the dominant gene. The recessive trait may be expressed when the recessive genes are in homozygous condition or when the dominant gene is not present.
What gene is recessive?
A recessive gene is a gene whose effects are masked in the presence of a dominant gene. Every organism that has DNA packed into chromosomes has two alleles, or forms of a gene, for each gene: one inherited from their mother, and one inherited from their father.
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.
What is meant by dominant and recessive genes Class 10?
– Dominant refers to the relationship between two versions of a gene. If the alleles (two versions of each gene) of a gene are different, one allele will be expressed as Dominant gene while the other allele effect is called recessive.
