The phenotype of an organism is the way that organism looks or the trait that it has. If a person’s genotype was Ee, then their phenotype would be unattached earlobes.
What is genotype EE?
The person with the Ee genotype is heterozygous for the trait, in this case, free earlobes. An individual is heterozygous for a trait when it has two different allelic forms of a particular gene. The heterozygous individual received one form of the gene from one parent and a different allele from the other parent.
Is EE dominant or recessive phenotype?
The allele E is dominant over e or from a point of view from allele e: it is recessive to allele E. A dominant allele is an allele that has an effect on the phenotype not only when it is homozygous but also when it is heterozygous. When allele E is dominant over e, EE and Ee have the same phenotypic value.
Is EE a dominant trait?
For example, the heterozygous genotype for earlobe type (Ee) produces detached earlobes because the dominant allele (E) hides the effects of the recessive allele (e). The homozygous dominant genotype (EE) also produces detached earlobes, so detached earlobes are considered the dominant trait.
What is the phenotype of attached earlobes?
Attached ear lobes are a recessive trait, or phenotype, in humans. In general, attached ear lobes are thought to be an example of single-gene pair…
What does EE mean in biology?
Term Meaning Genotype The set of genes possessed by an organism (e.g. EE, Ee or ee) Phenotype The physical characteristics of an organism (e.g. blue-eyed or brown-eyed) Alleles The different forms of a gene. For example the gene for eye colour has two alleles – blue-eyed or brown-eyed.
What is the phenotype of CC?
Finally, the albino, or “colorless” phenotype, cc, is expressed as white fur. In cases of multiple alleles, dominance hierarchies can exist. In this case, the wild-type allele is dominant over all the others, chinchilla is incompletely dominant over Himalayan and albino, and Himalayan is dominant over albino.
Is CC a heterozygous or homozygous?
All of the above results have involved comparisons of the heterozygote (Cc) with the homozygous recessive genotype (cc).
What is example of phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Examples of phenotypes include height, wing length, and hair color.
Is tongue rolling a phenotype?
An example of a gene that can be passed from a human parent to its offspring is the tongue rolling gene. … A person with the Rr genotype for tongue rolling would be able to roll his or her tongue, because he or she has the dominant allele that allows tongue rolling. So “tongue rolling” is his or her phenotype.
Is PP genotype or phenotype?
There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).
Is having brown hair a phenotype or genotype?
Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.
Is BB heterozygous or homozygous?
A bull with two alleles for a black coat is homozygous (BB). A calf that has one allele for red coat color and one allele for black coat color is heterozygous (Bb). Heterozygous individuals contain two different alleles which results in conflicting instructions.
Is attached earlobes autosomal?
Consider earlobe attachment. A single autosomal gene with two alleles determines whether you have attached earlobes or free-hanging earlobes. The allele for free-hanging earlobes (F) is dominant to the allele for attached earlobes (f). … Having free-hanging earlobes is an autosomal dominant trait.
