What are three characteristics that usually hold true for new alleles

The three characteristics are:

Dominant or recessive. Can be mutant. Inherited from the one parent. Explanation: The new allele means the allele in the genome of an offspring. The new allele can be dominant or recessive depending upon the power of its expression an phenotype. The allele is the distinct type of nucleotide sequence and part of the genome. This allele can be mutated in later life. The new allele is always inherited from one parent either father or mother and further changes can come from the mutations in sequence.
