Answer:

D) Genes for the two traits are located close together on the same chromosome, and crossing over occurred between the two gene loci.

Explanation:

According to the data shown above, we can see that at the crossing of the two flies the genes for the two characteristics are located close to each other on the same chromosome, and the crossing occurred between the two genetic loci.

As you may already know, a chromosome is a molecule formed by the correlation between DNA and proteins that keep the DNA compacted and prevent it from spreading.

Genetic loci, on the other hand, are regions on chromosomes where a specific gene for a specific trait is located.

Are Parakeets good starter pets? why or why not
pishuonlain [190]

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.
