which method compares traits between species to determine ancestor - descendant relationships?\na cladistics\nb punnett square\nc dihybrid cross\nd karyotype
Answer
Brief Explanations:
Cladistics is a method in biology that uses shared - derived traits to determine ancestor - descendant relationships among species. A Punnett square is used to predict the genotypes of offspring in a genetic cross. A dihybrid cross is a cross between two individuals that are heterozygous for two traits and is used to study the inheritance of two genes. A karyotype is a visual representation of an individual's chromosomes.
Answer:
A. Cladistics
