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.
What is ee phenotype?
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.
Is EE dominant or recessive?
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 are the 3 genotypes?
Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa.
How many dominant alleles are in this genotype EE?
Because individuals must have two alleles for a gene, there are three possible genotypes: EE is homozygous dominant (two dominant alleles) Ee is heterozygous (one dominant and one recessive allele) ee is homozygous recessive (two recessive alleles)
Is EE genotype or phenotype?
The expression of one’s genotype, such as EE, Ee or ee, is called one’s phenotype. For various reasons, certain genes may not express themselves.
What is the term genotype?
A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. … The expression of the genotype contributes to the individual’s observable traits, called the phenotype.
Is CC a heterozygous or homozygous?
All of the above results have involved comparisons of the heterozygote (Cc) with the homozygous recessive genotype (cc).
