How can two pea plants that have different genotypes have the same phenotype?
Mandira P. Same phenotype but different genotype is possible due to presence of dominant allele. A person can have a dominant allele on both the homologous chromosomes (i.e. in double dose) while another person may have single dominant allele and a corresponding recessive allele.
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.
Can different genotypes have the same phenotype?
The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive (tt) (Figure below).
What are the two possible phenotypes for peas?
For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible. Both the plants with red-red and red-white genotypes will have the red phenotype, while the plants with the white-white genotype will have the white phenotype.
How can two organisms with two different genotypes have the same phenotype?
Recessive alleles only demonstrate their effect if the individual has two copies of the alleles. Hence, due to the presence of dominant alleles in the genotype of organisms, phenotypes appear the same even though they differ in the genotypes.
Can two different genotypes result in the same phenotype?
Can organisms with different genotypes have the same phenotypes? The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive ( tt ) ( Figure below ).
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.
Can two different genotypes result in identical phenotypes?
The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive (tt) (Figure below).
Is the relationship between genotype and phenotype The same for different kinds of traits?
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
Can two genetically identical organisms display different phenotypes in life?
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.
What genotype is it when there are two identical alleles for a trait?
homozygous
