Are apple and peach genetically related (and how)?

Apples, peaches, & quince are all members of the rose family, Rosaceae.

Apples, quince, and pears are closely related. Some authorities place
them
all in the genus Malus. They are known as pome fruits ...

Anyway they are in the same subfamily, Maloideae, a coherent unit with
somewhat uncertain generic delimitation

Peaches nowadays are placed in the genus Prunus, along
with cherries, almonds, plums, apricots, & all the other stone fruits.

thank you all.

family Rosaceae
subfamily Maloideae: Apples, quince, pears
genus [Malus: Apples, quince, pears]
- this is contested.
really, apples and pears belong to different genera

genus Prunus: Peaches, cherries, almonds, plums, apricots,
& all the other stone fruits

How does this taxonomy relate to the genomes of pear and apple?
I may have used the term "genetic affinity" incorrectly.

I wonder whether the genome of apple and pear tells us anything
about their evolutionary relationship? Is their striking ressemblance
due to fundamental genetic similarities?

do they perhaps share whole chromosomes, or a significant number of genes,
are there certain types of mutation which could explain that one is a
descendant of the other etc.? for example, colza combines the genomes of
two other plants which belong to different genera. (which resulted in the
fact that the chromosomes didn't pair out, and so the original genomes
where preserved in the colza genome.) is there any sort of genetic relation-
ship like this between pear and apple?

hm... hope I don't bother you ( too much :-) ).
