Use the following information to answer questions 1 and 2 below. ***
Labrador Centronuclear Myopathy (CNM) is genetic disease in Labrador retrievers that results in insufficient muscle function, poor muscles tone, exercise intolerance, and awkward gait. CNM only develops in dogs that are homozygous recessive (pp) for the PTPLA gene. You are a dog breeder and there is one puppy in a new litter that has CNM. Neither of the puppy’s parents have CNM.
1. What are the parents’ genotypes for the gene responsible for CNM?
A) pp and pp
B) Pp and Pp
C) PP and PP
D) PP and Pp
2. Which of the following best describes the mother’s genotype?
A) Homozygous recessive
B) Heterozygous
C) Homozygous dominant
D) Heterozygous and Homozygous dominant
3. In biological systems most of the original energy from the sun is lost as?
A) Light
B) Kinetic energy of motion
C) Heat
D) Potential chemical energy
4. All of the following are common or recurrent themes in biology except?
A) Organisms grow, develop, and reproduce
B) Function determines structure
C) Matter is recycled while energy flows through living systems
D) Living organisms maintain homeostasis
E) Evolutionary processes explain both the unity and adaptive diversity of life
5. In the following chemical reaction, what is carbon dioxide (CO2)? Organic molecule + 6O2 ⇨ 6CO2 + 6H2O + energy
A) independent variable
B) product
