Based on the above information, the mutation type is frameshift mutation.
It is a genetic mutation caused by indels of various nucleotides in a DNA succession that is not detachable by three. The additions and erasures cause an adjustment in the length of a quality, which causes a movement in the codon perusing outline. A frameshift mutation happens when a protein is radically modified as a result of an addition or an erasure. Tay-Sachs illness is a human issue caused by a frameshift change.
Both parents' genotypes are Bb (brown blue)
the punnet square would be
BB(kid one) Bb(kid two) Bb(kid three) bb(kid four)
kid one will be homozygous for brown eyes. kid two and three will be heterozygous for brown eyes. kid four will be homozygous for blue eyes
in other words, 75% will have brown eyes. 25% will have blue eyes
