When offspring show a blend of the parents’ traits, one allele is dominant over the other. In complete dominance, the heterozygous phenotype lies somewhere between the two homozygous phenotypes. A heterozygous individual that exhibits the traits of both parents is an example of codominance.
When heterozygotes have a phenotype that is an intermediate between two homozygous phenotypes?
Incomplete dominance describes situations in which the heterozygote exhibits a phenotype that is intermediate between the homozygous phenotypes. Codominance describes the simultaneous expression of both of the alleles in the heterozygote.
Which pattern of inheritance occurs when a heterozygous individual’s phenotype is a blend of both homozygous individuals?
(Blending) Incomplete dominance is a phenotype of heterozygous individuals. An example would be hair color. (See both traits) Codominance is both phenotypes of both homozygous to be produced in heterozygous individuals.
What is the phenotype of a heterozygous?
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 the heterozygous phenotype of a single gene Cross appears as an intermediate of the two homozygous phenotypes This is known as?
Incomplete Dominance. a pattern of inheritance in which the heterozygous phenotype is intermediate between the two homozygous phenotypes.
What is phenotype example?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
When a heterozygous phenotype is intermediate This is an example of?
However, sometimes the heterozygote displays a phenotype that is an intermediate between the phenotypes of both homozygote parents (one of which is homozygous dominant, and the other of which is homozygous recessive). This intermediate phenotype is a demonstration of partial or incomplete dominance.
Is AA heterozygous or homozygous?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
Is BB heterozygous or homozygous?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.
What can you say about the phenotype of the offspring?
Answer: The phenotype is the trait those genes express. … Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene. This means there is a 100% chance of the offspring having brown eyes, or being BB.
What is the difference between homozygous and heterozygous?
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent.
