What genotype must the person have who possessed the recessive phenotypes?
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
A genotype consisting of two identical alleles of a gene for a particle trait?
it is a homozygous or heterozygous ( RR or rr)
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
What is the genotype of a person that is homozygous non sicklier?
RR since sickle cell is a recessive so a dominant trait means a non sicklier. If they have the trait it will be Rr which is heterozygous but RR is homozygous non sicklier.
How can you determine the genotype plant that displays the dominant form of a trait?
Do a testcross with a homozygous recessive plant.

What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.
How can you determine the genotype of a plant that displays the dominant of a trait?
Do a testcross with a homozygous recessive plant.

Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
Is the trait TT heterozygous or homozygous?
Yes.A homozygous genotype is a gene with two identical alleles. Recessive genes are represented by a lowercase letter. Thus, a homozygous recessive genotype would be two identical genes with lowercase letters.

RR since sickle cell is a recessive so a dominant trait means a non sicklier. If they have the trait it will be Rr which is heterozygous but RR is homozygous non sicklier.
What is a testcross?
Gregor Mendel devised the fundamental tool of the test cross. It is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype .
Is AA a homozygous genotype?
homozygous = AA & AA Heterozygous = Aa
How can you determine the genotype of a plant that displays the dominant form a trait?
Do a testcross with a homozygous recessive plant.
