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.
Can an organism have more than one phenotype for the same genotype?
Figure 3: Different genotypes can produce the same phenotype. … Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
Can different genotypes produce different phenotype?
An organism’s genotype is the set of genes that it carries. … However, since an organism’s genotype generally affects its phenotype, the phenotypes that make up the population are also likely to change. For example, differences in the genotypes can produce different 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).
How can two organisms have the same phenotype?
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.
How can individuals of the same species and even siblings have different characteristics?
Each gene can have several variants, called alleles, which code for different variants of the trait in question. Genes reside in a cell’s chromosomes, each of which contains many genes. … In species that reproduce sexually, each cell contains two variants of each chromosome, one inherited from each parent.
What are the physical characteristics called that are used to compare and contrast organisms?
The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype. Mendel’s hybridization experiments demonstrate the difference between phenotype and genotype.
Is it possible for two persons to have exactly the same genotype?
Unless you’re an identical twin, your genotype is completely unique. … Identical twins, however, share the exact same genotype, which is what makes them identical.
How many phenotypes are possible?
A fetus receives one of these three alleles from each of its parents. This produces four possible phenotypes (blood types) and six possible genotypes.
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.
