Influence of environment:<span> Environment can play several roles in influencing the expression of some genes. In hip dysplasia, for instance, environment can influence how dysplastic a dog becomes. A dog cannot become dysplastic unless it has a majority of "bad" hip genes. However, when a dog does have a majority of bad genes, and it is kept overweight or allowed to grow too fast, or is exercised too much or too little, that dog will end up with a worse case of hip dysplasia than it otherwise would have had.</span>
Codominance refers to a kind of dominance wherein the alleles of a gene pair in a heterozygote are completely expressed. This gives rise to an offspring exhibiting a phenotype, which is neither recessive nor dominant.
The examples of codominance comprise an individual with type AB blood group, which signifies that both the A and B allele are expressed equivalently.
