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 a phenotype have more than one genotype?
Phenotype = genotype + development (in a given environment). … Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa. With three alleles 1, 2, 3 there are six possible genotypes: 11, 12, 13, 22, 23, 33.
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.
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.
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.
How many different phenotypes are possible?
There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.
What is the relationship between genotype and phenotype?
The genotype of an organism is defined as the sum of all its genes. The phenotype of an organism is the observable physical or biochemical characteristics of an organism, determined by both genetic make-up and environmental influences.
