Answer:

A mutation is a change or group of changes that occur in the genetic material of an organism. A point mutation is a type of mutation where a single nucleotide base is changed, inserted or deleted from DNA or RNA sequence. Point mutation occurs due to DNA replication, exposure to radiations like UV and X-rays, extreme heat and chemicals.

Bezzdna [24]

Answer:

four phenotypes appear in the ratio 9:3:3:1

Explanation:

<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>

The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.
