A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
What else can I help you with?
What happens to the recessive allele in a heterozygous offspring?
In a heterozygous offspring, the recessive allele is present but not expressed because the dominant allele masks its effects.
What type of alleles are expressed only if two identical copies exist on the homologs of the offspring?
Recessive alleles are expressed only when two identical copies exist on the homologs of the offspring. In this case, if an individual inherits two copies of the recessive allele, it will show the recessive trait.
What is a reccessive trait?
the characters and habits that the offspring does not carry of the parents is known as recessive characters. example-woman-curl hair and fair body man-straight hair and black body. offspring-curl hair and black body in the above example, fair body and straight hair are the recessive characters that the child does not carry.
Is it true that recessive alleles are never present when dominant alleles are present?
No, recessive alleles can still be present in an individual's genetic makeup even when dominant alleles are present. In this case, the recessive allele may not be expressed phenotypically, but can still be passed on to offspring.
Why is it impossible for offspring to show the recessive trait if one parent is homoygous for the dominant trait?
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.
What makes a dominant allel different from?
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.
What is a gene pair that consists of a dominate allel and a recessive allel?
That is called heterozygous or it is called a hybrid.
What happens to the recessive allele in a heterozygous offspring?
In a heterozygous offspring, the recessive allele is present but not expressed because the dominant allele masks its effects.
When an allel is described by a lower-case letter it is a?
recessive
How are traits categorized for the offspring?
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.
For a recessive trait to be expressed in a generation of offspring an individual must be a?
Homozygous
What is an individal that has one recessive and dominant allel for pure bread?
Heterozygote.
What types of alleles are expressed only if 2 identical copies exist on the homologs of the offspring?
Two copies of the recessive allele are the only way a recessive trait is expressed phenotypically.
What type of alleles are expressed only if two identical copies exist on the homologs of the offspring?
Recessive alleles are expressed only when two identical copies exist on the homologs of the offspring. In this case, if an individual inherits two copies of the recessive allele, it will show the recessive trait.
What is RY506?
506 is allel variant of ry gene in Drosophila melnaogaster (The common fruitfly). The normal ry allel is recessive and prodiuces brown-orange produces
What is it called when replication is messed up?
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.
What is a trait that needs two factors in order to be expressed?
Actually, it is the recessive.................................................................UR WELCOME! :)
