Differentiate between
(a) Genotype and Phenotype
(b) Character and Trait
(c) monohybrid and dihybrid cross (phenotypic ratio).
Answers
Answer
A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.
The main difference between trait and character is that a trait is a state of a character, which is a distinct variation of a phenotypic characteristic of an organism whereas a character is a recognizable feature, which helps in the identification of the organism.
Monohybrid cross is used to study the inheritance of a single pair of alleles Dihybrid cross is used to study the inheritance of 2 different alleles
Answer:
1) A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.
2) The main difference between trait and character is that a trait is a state of a character, which is a distinct variation of a phenotypic characteristic of an organism whereas a character is a recognizable feature, which helps in the identification of the organism.
3)A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.
