What is phenotype 12 biology?
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.
What is the phenotype of an individual?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What are the 3 phenotypes?
If the only alleles for hair texture were straight and curly, there would be three phenotypes: straight, curly, and wavy. However, you asked for something a little different. You wanted three phenotypes that are all equally represented in the population.
What is genotype class 12th?
Complete answer: The genotype is called the genetic makeup of an organism that describes a complete set of genes in an organism. Humans are diploid organisms, they have two alleles for each genetic position or locus, with one allele inherited from a single parent. Each pair of alleles shows the genotype of a gene.
What is genotype and phenotype Class 12?
The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics. Whereas the phenotype is the physical appearance or characteristic of the organism.
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.”
How many phenotypes are there?
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 phenotype example?
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 are my phenotypes?
Phenotype Definition Phenotype is a description of your physical characteristics. It includes both your visible traits (like hair or eye color) and your measurable traits (like height or weight). The set of genes you carry (known as your genotype) is what determines your phenotype.
What is genotypic and phenotypic?
The genotype refers to the genetic material passed between generations, and the phenotype is observable characteristics or traits of an organism.
What is the phenotypic ratio of 1B B B?
B B 100% BB homozygous dominant – Black 7 .A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (tan is the recessive color). What are the phenotypic ratios of the offspring? 1 BB: 1Bb- 100% brown
What is the percentage of color-blind by genotype?
How many/what percentage of each could be expected? 25% Color blind female 25% Carrier female 25% Normal male 25% Color blind male 3.A boy, whose parents and grandparents had normal vision, is color-blind. What are the genotypes for his mother and his matemal grandparents.
What is the phenotypic ratio of a cross between yytt pea plant and yytt pea?

What is the genotype of mother and father with O blood group?
18. Mother and father of a person with ‘O’ blood group have ‘A’ and ‘B’ blood group, respectively. What would be the genotype of both mother and father? a. Mother is homozygous for ‘A’ blood group and father is b. Mother is heterozygous for ‘A’ blood group and father is c. Both mother and father are heterozygous for ‘A’ and ‘B’ blood d.
