Question

A normal pea plant bearing colored flowers suddenly starts producing white flowers. What could be the possible cause?

Answer 1

Each gene made up of two alleles, one from the mother and the other from the father. These alleles might be dominant or recessive. Even if only one copy of the dominant characteristic exists, dominant traits are always displayed when the linked allele is dominant. Only when both of the related alleles are recessive are recessive traits expressed. The linked feature is less likely to manifest if one of the alleles is dominant.

Complete answer:
There are two probable explanations: the coloured trait gene was a dominant and inhibited expression of the white gene for many generations; or the coloured trait gene was dominant and for many generations, the white gene not expressed.
Mutation is responsible for the emergence of white blooms.
Genetics is the study of the functioning and major codes of variation and heredity. Inheritance is the foundation on which heredity is built. It is described as the process of passing down qualities from one generation to the next. For his discoveries on the fundamental principles of heredity, Gregor Johann Mendel is renowned as the "Father of Modern Genetics."
Genes, like chromosomes, are arranged in pairs. A human being's parents each have two copies of their genes, and each parent transmits one copy of their genes onto their offspring. This is why the child shares many features with both parents, such as hair colour and eye colour.

Note:
A trait is a characteristic that is influenced by one or more genes. Certain features are also caused by abnormal genes and genes generated as a result of new mutations. The size of genes varies depending on the code or protein they create. The DNA of every cell in the human body is identical. The difference between the cells is due to the different types of genes that are activated, resulting in a range of proteins being produced.
