How can two organisms with two different genotypes have the same phenotype?
Genotype is the alleles, or the genetic makeup for the organism. Organisms can have the same phenotype when (1) they both have dominant alleles; for example TT or (2) are hybrids; for example Tt. Since the dominant allele will be expressed in the hybrid, both of these cases will produce the same phenotype.
How can two organisms have the same phenotype but different genotypes quizlet?
The combination of alleles in the offspring. … The masking of recessive alleles can result in organisms with the same phenotype but different genotypes. Organisms with two dominant alleles (homozygous dominant and one recessive allele (heterozygius).
How can two organisms with different genotypes for a particular inherited trait be identical in phenotype?
The phenomenon of dominant phenotypes arising from the allele interactions exhibited in this cross is known as the principle of uniformity, which states that all of the offspring from a cross where the parents differ by only one trait will appear identical.
What genotypes result in the same phenotype?
An Aa genotype can result in the same phenotype as either an AA or aa genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
Why don t similar genotypes produce the same phenotype?
Why don’t similar genotypes always produce the same phenotype? Animals display different phenotypes dependent on diet, not genotype. … the allele’s frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change.
Which statement describes how two organisms may show the same trait yet have different genotype for the phenotype?
Which statement describes how two organisms may show the same trait, yet have different genotypes for that phenotype? Both are homozygous for the dominant trait.
Is it possible for two organisms to have the same physical characteristic but have a different genetic makeup?
MESSAGE. A single genotype may produce different phenotypes, depending on the environment in which organisms develop. The same phenotype may be produced by different genotypes, depending on the environment.
The phenotype is an organism’s physical appearance, and the genotype is the genetic makeup.
