How does the structure of phylogeny charts explain homologous structures in organisms?

new species branch off ancestral species, so two species can have similarities in body structure.

all old species die off as soon as new species emerge, which explains why current species have traits of extinct species.

in different lineages of organisms, two organisms may have similar structures that evolved in different ways.

all organisms mutate their genome automatically when an environment changes, creating new traits and structures.

All organisms mutate their genome automatically when an environment changes, creating new traits and structures.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
