What else can I help you with?
What is it called When the heterozygotes display two phenotypes at the same time?
This is known as codominance, where both alleles in a heterozygous individual are expressed equally and simultaneously, resulting in a unique phenotype that shows characteristics of both alleles.
How is codominance an exception to the laws of genetics proposed by Mendel?
Its an exception because both of the alleles are expressed in heterozygotes.
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
How do you know that a pea plant with wrinkled seeds does not have one copy of the round seed allele?
The trait associated with the allele is not expressed in heterozygotes.
Why phenotypes don't always express its entire genotype?
Phenotypes are the entirety of the observable traits. Genotypes are the instructions in the genetic code. Dominant alleles override the recessive alleles, making only the dominant alleles expressed.
What is it called When the heterozygotes display two phenotypes at the same time?
This is known as codominance, where both alleles in a heterozygous individual are expressed equally and simultaneously, resulting in a unique phenotype that shows characteristics of both alleles.
What is hidden in the heterozyotes?
Heterozygotes have two different alleles for a particular gene, where one allele is dominant and the other is recessive. The recessive allele is "hidden" in heterozygotes because it is not expressed phenotypically but can be passed on to offspring.
How is codominance an exception to the laws of genetics proposed by Mendel?
Its an exception because both of the alleles are expressed in heterozygotes.
How is phenotype expressed in a incomplete dominance?
It's expressed when a heterozygous phenotype is between two homozygous phenotypes.
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
How do you know that a pea plant with wrinkled seeds does not have one copy of the round seed allele?
The trait associated with the allele is not expressed in heterozygotes.
Dominant alleles are so called because under most circumstances they?
are phenotypically expressed. They are expressed in homozygous form and in heterozygotes with the recessive allele. Recessive alleles are only phenotypically expressed in homozygous form. Consider two alleles for flower color, A and a, where A is dominant and expressed as red, and a is recessive and expressed as white. There are only three diploid genotypes possible for these alleles: AA Aa and aa.However, because A is dominant, the following phenotypes will be expressed for the following genotypes:AA: redAa: redaa: white
How are sex-linked genes expressed differently in the phenotypes of male and female?
i don't have any idea
How many different phenotypes can be produced by a pair of co-dominant alleles?
Three. Each homozygous genotype will have one phenotype each, and the heterozygote will have a third. Unlike incomplete dominance, where the heterozygote's phenotype is a blending of the two homozygous ones (i.e. crossing homozygous red and homozygous white snapdragons results in pink heterozygotes), codominance means the phenotype for each allele is seen in the heterozygote. An example can be seen in the Andalusian fowl. The two homozygotes have black and white plumage respectively, but heterozygotes appear blue, due to the presence of a fine mosaic of black and white areas (no blending).
How are Genotype phenotype different?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
What best describes phenotypes?
traits. your welcome! yall lil cheaters! lol (:
Pattern of inheritance in which both alleles contribute to the phenotype of the organism?
The pattern of inheritance in which both alleles contribute to the phenotype of the organism is codominance. For example white and red hair color in cattle. Black and white feather color in certain chickens.
