Answer:
C. Both light tan and dark tan body color provided an advantage to the crabs on this beach, but not necessarily in other crab habitats.
Explanation:
The changes in the number of light tan and dark tan body color of crabs that occured can be described as a diversifying or disruptive selection.
This disruptive selection occurs when individuals with extreme traits on both ends of the spectrum become selected against individuals of ntermediate or medium traits.
In the case of the crab, their environment favors the selection of both extreme values as against those intermediate individuals, as both light tan and dark tan body color of the crabs gives them advantage over others in this particular environment. This may only be obtainable in this environment or similar beach environment with the same settings and conditions.
A macromolecule is a large molecule containing many atoms. The four type are carbohydrates, lipids, proteins, and nucleus acids.
Answer:
The correct answer is - d. codominance.
Explanation:
Complete dominance is the pattern of inheritance where one allele masked the other allele completely in a heterozygous condition. Incomplete dominance is a pattern of inheritance where both the alleles blend or form intermediate phenotype in heterozygous condition.
The codominance pattern of inheritance is similar to the incomplete dominance but instead of making a blend of both alleles, it expresses both alleles together in patches or pattern.
