Genetics overview

Creatures' genetics tools let you track frozen and fresh breeding material (semen straws, embryos, eggs, and more) alongside your animals, so collection, storage, sales, and the offspring they produce all stay connected on one platform. Instead of a spreadsheet that only you can read, every straw and embryo becomes a record that carries its source animals, its counts, and its outcomes, which is what lets buyers see real lineage and proven-producer history.

Your genetics dashboard

Open Genetics from your Dashboard to see everything at a glance: how many items you hold, your available, sold, and used counts, your active marketplace listings, and a feed of recent activity.

The three buttons across the top are your starting points, and each leads somewhere specific:

• Add genetic material opens the form to log a new item by hand. This is how most material enters your inventory. See Managing your Genetic Inventory.
• Import brings in records you already keep elsewhere (a spreadsheet, for example) rather than retyping them.
• List for sale starts a marketplace listing from an item you already hold. You list from inventory, so the sale stays linked to the source material and its lineage. See Listing genetics on the marketplace.

What you can track

Creatures supports the material types breeders actually work with, and each one captures the details that matter for that kind of material:

• Straws (semen), tracked by straw count, with an optional sex-sort label (conventional, female-sorted, male-sorted, or mixed).
• Embryos, tracked individually with a sire and a dam, and optionally a recipient animal so an embryo transfer is followed through to pregnancy.
• Oocytes, unfertilized eggs collected from a donor female.
• Hatching eggs, fertile eggs set for incubation, with optional fertility history, an expected hatch date, and an NPIP number.
• Roe (fish eggs), with an expected hatch date.
• Live juveniles, young animals tracked together as a count before they get individual profiles.
• Other, for anything that does not fit the categories above.

Each item is stored with a preservation method (frozen, chilled, fresh, live, or ambient), which tells you how it has to be kept and shipped. The full definitions of every type, preservation method, and status live in the genetics reference.

How material moves through its lifecycle

Every item carries running counts and a status, so its current state is never ambiguous:

• Available material is on hand and free to list, sell, or use.
• Held for buyer (reserved) is material briefly held while a marketplace buyer completes checkout. It is not sold yet, and it returns to Available if the buyer does not finish paying.
• Sold is material drawn down through a sale, on or off the marketplace.
• Used is material drawn down through use, such as breeding a female, transferring an embryo, or setting eggs to incubate. Use carries outcome-specific statuses too, like implanted in recipient, incubating, or hatched.

Keeping these current is what powers your inventory accuracy and the lineage and proven-producer information buyers see, because each outcome links back to the genetics that produced it.

Before you use a straw or embryo to breed, the coat color calculator and visualizer can predict the colors a planned pairing could produce, so you can plan matings around the look you are after.
