B. The oldest crust is closest to the mid-ocean ridge.
Answer:
For a cladogram the closer the organisms are, the closer they are related.
Explanation:
Each branching off represents a change in the species, so the closer they are, the more traits they will share
If we name the gene for sunflower height with A, then the genotypes tall sunflowers are Aa (heterozygous), AA (dominant homozygous) and for short ones aa (recessive homozygous).
If we name the gene for flower color with B, than the genotypes for yellow color are BB (dominant homozygous) and Bb (heterozygous) and for orange color bb (recessive homozygous). A cross between heterozygous for both traits and heterozygous for hybrid homozygous dominant for flower color:
P: AaBb x AaBB
