White feathers in canaries are dominant to yellow feathers. A heterozygous canary is crossed with a homozygous recessive canary.
Lera25 [3.4K]

<em>2:4 homozygous recessive; 50% heterozygous.</em>

Explanation:

I will be using the letter B to represent dominant alleles and b to represent recessive alleles.

If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).

If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).

I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...

<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.

<u>50%</u> of the offspring will be <u>heterozygous</u>.

Simulate a 24-hour day (12 hours of light, 12 hours of dark). How many snails and plants do you need to keep a stable environmen
Lisa [10]

Answer:

One snail for two plants.

Explanation:

One snail and two plants we need to keep a stable environment because the snails help to clean up garden debris by feeding on them and their feaces has nitrogenous nature which is nutritive for the plants. So the plants get nutrients from the snail as well as carbondioxide gas used by the plants for the process of photosynthesis. So we can say that snails are important for maintaining a stable environment.
