What is phenotype in Class 10?

Phenotype refers to the physical traits that are observed in an organism which are the outcome of the expression of the genes of an individual. The genotype determines the phenotype of an individual.

What is a phenotype in biology?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What is a phenotype in biology example?

phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.

What is phenotype simple?

“Phenotype” simply refers to an observable trait. “Pheno” simply means “observe” and comes from the same root as the word “phenomenon”. And so it’s an observable type of an organism, and it can refer to anything from a common trait, such as height or hair color, to presence or absence of a disease.

What is genotype and phenotype in biology?

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.

What is phenotypic expression?

Phenotypic expression is the result of a complex interplay between an organism’s genes and its environment. During growth and development, organisms undergo a programmed series of phenotypic changes. … The ability to vary phenotypic expression in response to environmental conditions is known as “phenotypic plasticity.”

What is a cell phenotype?

Cellular phenotype is the conglomerate of multiple cellular processes involving gene and protein expression that result in the elaboration of a cell’s particular morphology and function. … This single-cell study permits high resolution of molecular and functional components that underlie phenotype identity.

What do you mean by plasmid?

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell’s chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.

What is the difference between H * * * * * * * * * and heterozygous?

While individual organisms bearing different alleles (Rr) are known as heterozygous.

Homozygous vs Heterozygous.

Homozygous Heterozygous
Contains only one type of allele, either dominant or recessive Contains different alleles for a trait. Both dominant and recessive
