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 organisms have the same phenotype but different genotypes quizlet?
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 but different genotypes Brainly?
Answer; This is because the genotype may be have recessive effects or dominant effects. For example; Genotype RR AND Rr are going to produce the same phenotype and look the same, but the one with the Rr has recessive gene.
Can 2 people have the same phenotype?
Due to the presence of a dominant allele, the same phenotype but distinct genotype is possible. … On both homologous chromosomes, a person can have a dominant allele, while another person may have a single dominant allele and a corresponding recessive allele.
Can you determine a genotype based on phenotype?
Today, scientists use the word “phenotype” to refer to what Mendel termed “external resemblance” and the word “genotype” to refer to an organism’s “internal nature.” Thus, to restate Mendel’s musing in modern terms, we cannot infer an organism’s genotype by simply observing its phenotype.
Is a phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What is the difference between phenotype and phenotyping?
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.
Is a genotype?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. … Each pair of alleles represents the genotype of a specific gene. For example, in sweet pea plants, the gene for flower color has two alleles.
Is it possible for two organisms to have the same physical characteristic but have a different genetic makeup?
Two individuals that are genetically different may develop differently in the same environment, but two genetically identical individuals may develop differently in different environments. The model of Figure 1-20 applies here. In general, we deal with organisms that differ in both genes and environment.
