In a(n) pedigree, nodes with the same parents are called twins or siblings. Which type of diagram is being described?
A

B
Karyotype
C
Pedigree
D
Punnett square
Verified step by step guidance1
Understand the definition of the terms given: A 'pedigree' is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors from one generation to the next.
Recognize that in a pedigree, nodes represent individuals, and those with the same parents are siblings or twins, which fits the description given in the problem.
Compare the other options: A 'phylogenetic tree' shows evolutionary relationships, a 'karyotype' is a picture of chromosomes, and a 'Punnett square' predicts genotype combinations from a genetic cross.
Conclude that the diagram described, where nodes with the same parents are siblings, matches the characteristics of a pedigree.
Therefore, identify the correct answer as 'Pedigree' based on the definition and the description provided.
