Question

Assertion:characters which can be observed or which is visible is called phenotype. Reason:if we consider the height of an organism , the phenotype may be tall or short

Answer 1

Answer:

Phenotype : It is an physical expression of an organism .

Explanation:

• We come across the crosses Mono-hybrid and Di-hybrid crosses .
• In them whether we take in to account one character or two characters at a time , the offspring inherits one mother and one father   gamete .
• We know, about Laws of segregation and Law of dominance .
• Accordingly, we get to see the first filial and second filial generations .
• It is seen that in first generation , all the offspring inherits one dominant and other recessive gene , as a result of fertilization .
• In second filial generation , the offspring produced have fixed phenotypic and genotypic ratio.

Phenotypic ratio of monohybrid cross

Dominant : Recessive trait

3:1

Genotypic ratio of monohybrid cross

1:2:1

Pure dominant : Hybrid : Pure recessive

Answer 2

The assertion is true but the reason is false.

Explanation:

• The phenotypes in genetics are a set of observable characteristics or traits of organisms. The term refers to the organism's morphology or the body. Hence refer to its physical form and development.

• The variations may occur in the phenotypes of the organism due to the underlying genetic variations. The behavioral phenotypes include cognitive, behavioral patterns, and personality. It may also include the disorders.
