Heterozygous is a description of the genotype, or combination of alleles present in an organism. The genotype gives rise to the phenotype. … In alleles that show complete dominance, the heterozygous phenotype will be the same as the dominant phenotype.
Is heterozygous a genotype or phenotype?
An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. … Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
Is phenotype heterozygous or homozygous?
Recessive alleles only express their phenotype if an organism carries two identical copies of the recessive allele, meaning it is homozygous for the recessive allele. This means that the genotype of an organism with a dominant phenotype may be either homozygous or heterozygous for the dominant allele.
Is homozygous an example of a phenotype?
For instance, one homozygous genotype for pea plant height is TT, which means it will have the phenotype “tall.” Genotype can also be homozygous for recessive genes as well.
How would you describe the phenotype of a heterozygous A?
A heterozygous individual is a diploid organism with two alleles, each of a different type. In alleles that show complete dominance, the heterozygous phenotype will be the same as the dominant phenotype. …
When a heterozygote has an intermediate phenotype?
This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.
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.
What is the phenotype of a heterozygous plant?
Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
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).
What is the difference between heterozygous and heterozygote?
Heterozygous. A diploid organism is heterozygous at a gene locus when its cells contain two different alleles (one wild-type allele and one mutant allele) of a gene. The cell or organism is called a heterozygote specifically for the allele in question, and therefore, heterozygosity refers to a specific genotype.
What is homozygote heterozygote?
A heterozygote is an individual having two different alleles at a genetic locus; a homozygote is an individual having two copies of the same allele at a locus.
What is heterozygous allele?
The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
What is an organism’s phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What is a homozygous phenotype?
A homozygous phenotype is the product of two identical genes.
