Scientists studying a species of fish using quantitative trait locus analysis found that fishes with paternal alleles at a marker have larger body sizes than fishes with maternal alleles at the marker. This suggests that

A) the alleles controlling body size are in a state of linkage disequilibrium.
B) the genetic marker itself has a direct effect on body size.
C) the loci that affect body size may be nearby the marker.
D) fish body size is a highly heritable trait.

Paternal Alleles

Genetic variants located on the chromosomes inherited from the father.

Linkage Disequilibrium

A situation in genetics where alleles at different loci are associated more frequently than expected by chance alone.

Heritable Trait

A characteristic or feature of an organism that can be passed from parent to offspring through genetic information.

  • Acknowledge the complexity of genetic differences and their role in determining traits.
