Can individuals with the same genotype have different phenotypes?
Individuals with the same genotype can also show different degrees of the same phenotype. Expressivity is the degree to which trait expression differs among individuals. Unlike penetrance, expressivity describes individual variability, not statistical variability among a population of genotypes.
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.
Is it possible for two organisms with the same genotype to have different phenotypes explain your answer?
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 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).
Do plants with the same phenotype always have the same genotype?
Plants with the same phenotype always have the same genotype. … – The F2 ratio of tall plants to short plants produced in a cross between two hybrid tall pea plants (Tt) is 3 tall plants for every 1 short plant. – Mendel observed that about 3/4 of the F2 offspring showed the dominant trait.
What are the differences between genotypes and phenotypes?
Genotype versus phenotype. 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. … For example, differences in the genotypes can produce different phenotypes.
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.
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.
