What is my genotype and phenotype?
What is my genotype and phenotype?
The two terms are often used at the same time to describe the same organism, but there is a difference between genotype and phenotype: An organism’s genotype is the set of genes in its DNA responsible for a particular trait. An organism’s phenotype is the physical expression of those genes.
What links genotype and phenotype?
The genotype—i.e., the genetic makeup of cells—and the phenotype have been in the limelight for decades. The genotype and phenotype have been linked through expression of the specific encoded proteins. The linkage has been understood in terms of the specific three-dimensional structures that they obtain.
What are the four genotype?
Because we define sex by the type of gonads, our shorthand refers to the four genotypes as XXF, XYF, XXM, and XYM.
What is genotype and phenotype in plants?
An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
What are phenotypes examples?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. Examples of phenotypes include height, wing length, and hair color.
What is the distinctive phenotype of the lin-12 GLP-1 double?
The distinctive phenotype of the lin-12 glp-1 double is called Lag, for ” L in-12 a nd G lp-1″.
What are the LIN-12 /Notch proteins?
C. elegans has two LIN-12 /Notch proteins, encoded by the lin-12 and glp-1 genes. These genes were identified through genetic screens for developmental mutants, and genetic analysis has established both unique and redundant roles for the two genes in specifying cell fates.
What are the lin-12(D) alleles?
The first alleles discovered, called lin-12 (d) alleles, were dominant and hypermorphic, and intragenic reversion yielded null alleles, called lin-12 (0) ( Greenwald et al., 1983 ).
Is there a role for lin-12 activity in cell fate specification?
Possible roles for lin-12 activity in differentiation or function, as opposed to cell fate specification per se, have also been described ( Eimer et al., 2002; Chao et al., 2005 ).
