The genotype is expressed when protein and RNA molecules are made using the information encoded in the DNA of the genes. Due to the presence of a dominant allele, the same phenotype but distinct genotype is possible.
How can the same genotype have different phenotypes?
The same genotype, when raised in different environments results in different phenotypes. Furthermore, different genotypes respond to the same environmental changes differently from each other.
Can organisms with the same genotype have different phenotypes Why?
Even two organisms with identical genotypes normally differ in their phenotypes. … Identical twins share the same genotype, since their genomes are identical; but they never have the same phenotype, although their phenotypes may be very similar.
How can the same genotype lead to multiple phenotypes?
Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.
How can identical twins have the same genotype but different phenotypes?
Identical or monozygotic twins occur when a single egg is fertilised to form 1 zygote that divides into 2 separate embryos. As a result, identical twins share identical DNA but may show differences in their phenotype due to environmental factors.
How is it possible that two organisms can have the same phenotype but different genotypes for a specific trait give a specific example to support your answer?
If two individuals have a certain phenotype, it does not mean that they must have the same genotype. For example, the possible genotype of a pea plant that has a tall phenotype can be homozygous dominant (TT) or heterozygous (Tt). Overall, different genotypes can result in the same phenotypes.
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).
Can animals with the same genotype express different phenotypes?
Mandira P. Same phenotype but different genotype is possible due to presence of dominant allele. … In both the above cases the trait controlled by dominant allele will be expressed and hence there will be no distinction in phenotype. This phenomenon is seen in all organisms including plants.
What is the relationship between an individual’s genotype and phenotype and how can genotypes shape and interact with the environment?
An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment.
What is the process called when one genotype gives rise to a different phenotype under different environmental conditions?
Phenotypic plasticity can be defined as ‘the ability of individual genotypes to produce different phenotypes when exposed to different environmental conditions’ (Pigliucci et al. … As with any organismal trait, the way in which an individual responds to environmental influences is subject to evolutionary change.
Can identical twins have different genotype?
Box 2.1 Monozygotic and Dizygotic Twins
The result is the creation of two separate, but genetically identical offspring. … These two individuals share the same amount of genetic material as would any two children from the same mother and father. In other words, they possess a different genotype and phenotype.
