(A) Differentiate phenotype and genotype

• 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.
• Dysferlin deficiency will only cause muscle weakness (phenotype) if a person has two defective copies of the dysferlin gene (genotype).
• The genotype of two defective dysferlin genes is associated with two different phenotypes, the symptoms of LGMD2B or of Miyoshi Myopathy.

(B) Name the character which is hidden in the F1 generation and which got expressed in the F2 generation

• Mendel conducted monohybrid cross on pea plant and analyzed the result in the F1 and F2 generations.

Answer 2

Answer:

Explanation:

Phenotype refers to the physical observable characters

Genotype refers to the genetic makeup of an individual...

In Mendels pea experiment,

in f1 generation all plants were tall(homozygous and heterozygous)

the recessive character was not expressed.

In f2 generation both tall and dwarf plants appeared
