16.1A - In a species of river otters, having brown fur is dominant to black fur.
A brown male otter is cross-bred in captivity with a female who has black fur.
The pairing produces 6 otter pups; 4 of whom have brown fur, and 2 with black fur.
From these offspring, one can conclude:
Group of answer choices
The brown-furred father's genotype is homozygous recessive
The black-furred mother's genotype is heterozygous
The black-furred mother's genotype is homozygous dominant
The brown-furred father's genotype is heterozygous
The brown-furred father's genotype is homozygous dominant
The question cannot be answered without more information

16.2B - Most genetics research is performed on model organisms, such as fruit flies, bacteria, mice, peas, or corn. Why?
Place a check mark next to every reason why humans are not good genetics test subjects:
Hint: There are 4 correct answers
Group of answer choices
Humans have too few offspring to be statistically significant
Human life-spans and generations are too long
Humans only possess dominant traits since we are highly evolved mammals
Human genetics are usually non-mendelian, which makes them very complicated to study
Humans do not express observable phenotypes
Human genotypes are always the wild-type and show little variation
It is unethical to perform genetics experiments that require the forced mating of humans
