There are 4 chromosomes that are visible at the beginning of Mitosis.
Answer:
NO! They require a ton of attention, a large cage, and experience with birds. Parakeets are often marked as starter pets, but no, they are not.
First, they need a 3 feet long cage with 5+ toys that need to be changed each month. And they need natural perches, not the cheap wooden dowels, they will get feet problems. Most people don't do this, having a bored pet.
Second, parakeets will chew anything given/available to them, and a lot of things can be toxic to them, which can lead to the death of your pet.
Third, parakeets are messy and noisy. They poop a LOT and love to toss seeds around their cage. They also need millet and a calcium chew, which are also messy.
They also will want a friend, they are flock animals in the wild so 3-4 birds is a good number, but getting more birds means getting a large cage. The pet store will tell you it's fine, but it is not. ALWAYS SEEK HELP FROM A BIRD BREEDER.
Lastly, they need a bird proofed room to fly around in. No matter how large your cage is, they still need some out-of cage time.
Try a dove or pigeon instead, they are listen the #1 easiest and cheapest to care for pet bird.
