Question

What is a genotype and phenotype ratio?

Answer 1

Gene

1. The smallest hereditary unit controlling a specific function is the gene.
2. It is a segment of DNA.
3. It is located on chromosomes.
4. Alternative forms of genes are called alleles.

Genotype

1. The genotype of an organism refers to its genetic makeup.
2. It is inherited from parent to offspring.
3. For example - AA, Aa, and aa (Genes for flower color )

Phenotype

1. Phenotype refers to the observable characteristics of an organism.
2. The phenotype is not passed on from one generation to the next.
3. The same phenotype can belong to the same genotype or not.
4. For example - AA or Aa codes for purple color flower, and aa codes for white flower.
5. Here, the phenotype expressed by the genes AA and Aa is purple, and the phenotype expressed by the gene aa is white.
