codominance. when both alleles can be independently observed in a phenotype.
When both alleles can be observed in a phenotype?
A phenotype is how the trait appears, but a genotype is the two alleles that cause the phenotype. How is incomplete dominance different than codominance? In incomplete dominance, the parents’ phenotypes blend together in the offspring, but in codominance, both of the parents’ phenotypes can be seen in the offspring.
When both alleles are the same it’s called?
If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.
What are the two alleles that control the phenotype?
Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive. The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.
What is multiple alleles give an example?
Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. Alleles are different or contrasting forms of a gene. For example, for the gene encoding for height, one allele can be for tallness, whereas the other can be for dwarfness.
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.
What do multiple alleles mean?
: an allele of a genetic locus having more than two allelic forms within a population.
What is the best definition of allele?
Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.
