During the formation of a sperm cell in a male salmon, a mutation produces a new allele. The sperm cell fertilises an egg and an offspring develops. Which outcome follows from this information?
The offspring inherits the new allele only if the egg carries the same allele
The new allele is found in only some of the offspring's body cells
The offspring inherits the new allele from the male parent
The offspring inherits the new allele only if the male parent's phenotype changes
