Do further testing on the species to discover whether or not the species is related.

A male drake will result with XY chromosome and a female drake would have XX chromosomes
The most appropriate technique that the physician should use to estimate the basal metabolic rate of Louisa's body is indirect calorimetry.
<h3>What is indirect calorimetry?</h3>
Indirect calorimetry is a medical technique for determining a person's resting energy expenditure. This technique is used to calculate the calories your body expends in a resting situation.
Information obtained from indirect calorimetry can be used as a guide to basal metabolism to determine whether it is normal, increased, or decreased.
Based on the above, this is the best technique the doctor has to find out why Louisa is gaining weight without changing her diet.

(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.
(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.
(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
