Therefore "the copperheads are subspecies and the cottonmouth is a separate species".
<u>Answer:</u> Option C
<u>Explanation:</u>
The higher classification is "copperhead" for both the subspecies Agkistrodon contortrix contortrix and Agkistrodon contortrix mokasen. As the name itself consist species name "A. contortrix", both are belonging from "Viperidae" family, "Crotalinae" subfamily and venomous pit viper subspecies.
These are generally silent snakes as they show lazy and motionless behavior when encountered but on agitating sufficiently they become protectively aggressive and they are species of eastern North America. While Agkistrodon piscivorous are separate species with higher classification as "Cottonmouth" and name carry species name "A. piscivorus". It is indigenous to southeastern United States and belongs to same family as copperhead.
Complete question:
A female is born with attached earlobes, which is a recessive phenotype. Which of the following statements about her parents must be true?
a. neither has the codominant allele.
b. Her father has an inactivated allele.
c. Both parents have the recessive allele.
d. Her mother carries the dominant allele.
Answer:
c. Both parents have the recessive allele.
Explanation:
A recessive trait is expressed in homozygous recessive genotypes only. If a female expresses the attached earlobe phenotype, she should be homozygous for the allele since the attached earlobe is a recessive trait. If allele "a" gives attached earlobe phenotype in homozygous genotype, the genotype of the female would be "aa". This means that the female has got one copy of the allele "a" from her either parents. Therefore, both her parents should have at least one copy of the recessive allele "a".
