Can different genotypes have the same phenotype?
Since the phenotype is the result of an interaction between genes and the environment, different environments can lead to different traits in individuals with a particular genotype. In addition, different genotypes can lead to the same phenotype. This happens because genes have different alleles.
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.
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.
Why can individuals with different genotypes have the same phenotype quizlet?
Each parent provides its offspring with one allele if every gene, so that the offspring inherits a pair if alleles for every gene. The combination of alleles in the offspring. … The masking of recessive alleles can result in organisms with the same phenotype but different genotypes.
When many different genes are associated with the same phenotype?
There is a one-to-many relation of genes to phenotypes. This relation is called pleiotropy, which is inferred from the observation that mutations selected for their effect on one specific character are often found to affect other characters of the organism.
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.
How can two plants that have different genotypes for a particular inherited characteristics be identical in phenotype?
Therefore, the two possible heterozygous combinations produce offspring that are genotypically and phenotypically identical despite their dominant and recessive alleles deriving from different parents. They are grouped together.
What is meant by founder effect?
The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony. The new population may be very different from the original population, both in terms of its genotypes and phenotypes.
When using Hardy-Weinberg equilibrium What do we assume that?
The Hardy-Weinberg equilibrium principle describes the unchanging frequency of alleles and genotypes in a stable, idealized population. In this population we assume there is random mating and sexual reproduction without normal evolutionary forces such as mutation, natural selection, or genetic drift.
Why is the Hardy-Weinberg model useful?
Importance: The Hardy-Weinberg model enables us to compare a population’s actual genetic structure over time with the genetic structure we would expect if the population were in Hardy-Weinberg equilibrium (i.e., not evolving).
How can two plants that have different genotypes have the same phenotype quizlet?
Homozygous plants have two identical alleles for a particular trait, TT or tt. In contrast, heterozygous plants have two different alleles for a particular trait, Tt. How can two plants that have different genotypes have the same phenotype? … In codominance, the heterozygous phenotype shows both traits.
What’s the difference between genotype and phenotype quizlet?
The phenotype is an organism’s physical appearance, and the genotype is the genetic makeup.
