What type of allele dominance occurs when both alleles are active and expressed?
Either Co-dominance, where different parts of the organism display the different alleles (i.e. red and white flowers), or a combination of the two alleles (i.e. red and white alleles make pink flowers)
How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
What type of allele dominance occurs when both the alleles are active and expressed?
When both the alleles are expressed, it is called co-dominance or mixed dominance.
What is Gregor Mendel contribution?
He paved the road to the study of heredity or inheritance. He discovered how inheritance occurs and how traits are expressed through alleles and he proposed the idea of dominant and recessive alleles.
What is the creation of new combinations of alleles called?
The creation of new combinations of alleles is called genetic recombination. This process occurs during meiosis when homologous chromosomes exchange genetic material, leading to the formation of unique combinations of alleles in offspring.
What occurs when alleles are equally dominant?
it is a an complete dominance also known as codominance that is correct nice job
What is the condition called when two alleles for a trait are both dominant and a blend of the two occurs?
Incomplete Dominance
Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
What is the difference between codominance and multiple alleles?
Codominance occurs when both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays characteristics of both alleles, such as in blood type AB. Multiple alleles refer to the existence of more than two alternative forms of a gene within a population, allowing for a variety of genotypes and phenotypes, like the ABO blood group system where three alleles (A, B, O) determine blood type. While codominance describes the expression of alleles, multiple alleles describe the variety of alleles available for a trait.
How does codominance effect phenotype?
Codominance occurs when both alleles contribute to the phenotype of a heterozygous individual. This results in a phenotype that displays characteristics of both alleles simultaneously, rather than blending them. This can lead to unique patterns or color combinations in the phenotype.
What does it mean if a trait demonstrates codominace?
Co-dominance occurs when two different alleles at a gene locus produce and intermediate result. In shorthorn cattle the combination of the white and red alleles produces roan. In poinsettia plants the combination of red and white alleles results in pink.
Which statement is TRUE about multiple alleles?
MULTIPLE CHOICES a. It happens when two or more alleles control the inheritance of a character. b. It refers to traits that are controlled by genes located on the same-sex chromosomes. c. It occurs when two dominant alleles of a contrasting pair are fully expressed at the same time in a heterozygous individual. d. It occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents.
