A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
A recessive allele is expressed if in the genotype there are two recessive genes. If there is a dominant gene it will mask the recessive.
The recessive trait shows when the offspring has two recessive alleles and no dominant allele (aa instead of AA or Aa).
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called Recessive traits. - Nikkkki
Because the parent with the homozygous alleles for the dominant trait can only pass on that dominant allele to its offspring and the dominant allele, if present, is always expressed.
A recessive gene A recessive gene makes it harder for genes(or traits) to be passed on from parents to daughters.
if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.
Recessive traits can be hidden if the organism inherits one dominant and one recessive allele (i.e. is heterozygous) for a gene. If a heterozygous organism mates with another heterozygous organism for the same trait, the recessive trait may be expressed in their offspring, which would mean that the offspring inherited two recessive alleles, one from each parent.
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
That is called heterozygous or it is called a hybrid.
Homozygous
As traits are dispensed to the offspring they can be either dominant or recessive. A recessive trait is only expressed when two identical alleles exist.
recessive
Two copies of the recessive allele are the only way a recessive trait is expressed phenotypically.
Heterozygote.
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
Actually, it is the recessive.................................................................UR WELCOME! :)
Recessive because...
The dominant allele will always show over the recessive, and both can be passed onto the offspring. To find out exactly which genotypes the children can have you need to make a punnet square!
506 is allel variant of ry gene in Drosophila melnaogaster (The common fruitfly). The normal ry allel is recessive and prodiuces brown-orange produces
