Yes, a mutation is a type of change because that's what a mutation is basically. For example when people are born with down syndrome that occurs because early in development when the chromosomes get copied over a mutation occurs causing them to have two copies of 21 chromosomes (some people even have three copies of 21 chromosomes.

For three traits inherited in a dominant/recessive pattern, what is the probability of an offspring in a trihybrid cross between
AleksandrR [38]

Answer: For three traits inherited in a dominant/recessive pattern, the probability of an offspring in a trihybrid cross between parents heterozygous for all three traits to be recessive at exactly two of the three loci is 23/64.

Explanation: Let A, B and C represent the dominant alleles and a, b and c represent the recessive alleles. The genotype of each of the parent will be AaBbCc since it has been said to be heterozygous for all the three traits. There are eight (8) possible different types of gametes from each of the genotype. This can be calculated using 2^n where n is the number of heterozygous loci.

The number of heterozygous loci in the genotype AaBbCc is three (3). 2^3 = 8. The gametes are;

ABC

ABc

AbC

Abc

aBC

aBc

abC and

abc.

Therefore, sixty-four possible offsprings are expected from the cross AaBbCc x AaBbCc.

Out of these offsprings, twenty-three (23) are expected to be heterozygous at two loci as boldly shown in the attached image.
