mutation.
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
because when you take a gene from another species they don't always turn out the way you whant them to for example; if you take a gene from a blue plant and put it into a red plant you might get a verious of colour because somewhere in the family tree there would be a different colour of parents.
Paired fins are fins found in pairs on both sides of a fish's body. These fins play a crucial role in stability, maneuvering, and steering. Examples of paired fins include pectoral fins and pelvic fins.
Of course it does.

The trait that is not expressed when paired with a dominant allele is known as a recessive trait. It is masked by the dominant trait in individuals carrying both alleles.
expressed in the phenotype even when paired with a different allele.
An allele that always shows up in an organism's phenotype and masks the expression of another allele is called dominant. Dominant alleles are always expressed, even when paired with a recessive allele.
recessive (sraight out of my biology lesson!)
The dominant allele will always show physically in an individual, while the recessive allele will only be expressed if paired with another recessive allele.
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
A recessive gene is a gene that is only expressed if an individual has two copies of it, one inherited from each parent. In the presence of another dominant gene, the recessive gene's trait is not expressed.
Alleles are different types of a gene. Each gene controls a characteristic and they is usually a recessive allele and a dominant one. The main similarity is that they both control a certain characteristic!
In genetics, alleles can be classified as either dominant or recessive. The term "homologous" refers to the pairing of chromosomes in meiosis. Whether an allele is dominant or recessive depends on its effect on the phenotype when paired with another allele. Homologous chromosomes do not determine the dominance of an allele.
