Step 7
Triur has had a previous partner and has produced numerous children. The female in question had a set of larger nostrils. Their (many) children show a variation in their nostril size. 211 individuals have smaller slits hidden mostly under their coats like their dad; 198 have larger nostrils.
Duine too has produced other offspring. His partner was a female with larger nostrils and they conceived of 86 children, all with with bigger nostrils but 16.
Beirt got tested and has shown to be homozygous. It is known that only two alleles are possible at this specific locus, called 'n'.
Beirt is especially interested in the nostril size as in warmer areas the larger nostril (and nasal cavity behind it) can help cool down the inhaled air before it enters the lungs. Which of the two males should Beirt choose if she wants the highest chance possible to produce children with larger nostrils? Make sure you show your arguments on paper..
