How to determine the bacteria species based on DNA sequence. Choose one DNA sequence and elaborate how you identify the bacteria.

In the Mexican Hairless breed of dogs, the hairless condition is produced by the heterozygous genotype (Hh). Normal dogs are homozygous recessive (hh). Puppies homozygous for the H allele are usually born dead, with abnormalities of the mouth and absence of external ears. If the average litter size at weaning is six in matings between hairless dogs, what would be the average expected number of hairless and normal offspring at weaning from matings between hairless and normal dogs?

There are three histologic specimens of cartilaginous tissue. Two of them are stained with

hematoxylin-eosin, and one histologic specimen is stained with orcein. What fibres and in what

type of cartilaginous tissue can be determined by such dyes? What functional properties of the

cartilaginous tissue do they cause?
