Presence of gills indicate the given mollusc is aquatic.

It may also presume that the short mouse parental is always Aa. And we get AA, Aa, Aa, Aa, and Aa situations once their matter and they fall pregnant to both high and short tail mice but we wouldn't get the fat tail mouse unless the tail-mouse were as AA.

we always get two types of lines. It demonstrates there was no uniform AA genera. It is a case of the heterozygous dangerous gene, that can cause a set of identical alleles inside an organism to always be lethal.
