Answer: Point mutation
There are several different types of mutations possible in the base sequence of DNA. If a GGC (glycine) codon were changed to UGC (cysteine), it would be termed a point mutation.
Explanation:
Point mutation is caused when a nitrogenous base (purine or pyrimidine) is substituted by another base of the same or different class in a nucleotide. So, GGC (glycine) codon to UGC (cysteine) signifies the change of the first base - guanine to uracil.
Other types of mutation include insertion and deletion.
But in this case, point mutation is said to have occurred.
The number of eggs laid by a chicken depends on a number of factors mainly includes the food it is being fed upon and it is properly fertilized or not.
Other factors also impact the egg laying capacity in chicken such as time of the year that means the number of daylight hours effect the egg laying capacity. The breeds of chicken also determine the number of eggs it lays. The age of hen is also a key important variable in terms of egg laying as maximum eggs are laid in the initial couple of years and then it decreases with age.
