Answer:
Reduced penetrance or incomplete penetrance
Explanation:
Penetrance refers to the extend which a certain gene or set of genes is expressed in a population.
It can be complete where there is expression of the gene in a population having it.
Whereas, in reduced penetrance is where the mutation is not expressed in every individual in the population having it.
For instance polydactyly exhibits reduced penetrance since the parents had the mutation it was not expressed it came to be expressed on their pedigree.
Offspring with a 3:1 ratio suggest that both parent that both parent that give rise to this offspring were both heterozygous. Heterozygous individual is someone who has two different allele at a locus whereby by one gene is dominant over the other gene. example of heterozygous parent is a parent Aa pair of alleles. In this pair gene A is dominant over gene a
certain hydrogen bonds are formed so that A goes with T and G with C
