Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (a

abb) with 6-cm ears is mated to a true-breeding male (AABB) with 16-cm ears. Predict the ear length of the F1 generation. (Note: Assume that each allele contributes equally to ear length, and the genes segregate independently. Also assume that environmental influence on ear length is negligible.)

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.

landscape management attracts people to nature preserves and national parks what are the benefits to the wildlife in these areas
Ket [755]

Answer:

one benefits to wildlife in national and nature parks are, that there are is not hunting within the parks. not only does this protect the wildlife, it also sustains the balance of life. nature and wildlife parks allow a careful eye to be placed on the animals that are going extinct or are even victims of severe hunting. this allows this generation as well as their future offspring to be healthy and ensure safety. a benefit to the public would be the, scenic routes you can walk on a trail, besides walking and being outdoors, any contribution/ donations are ensured to go towards rehabilitation of the animals.

Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

Name the things which help in the preparation of carbohydrates in plants​
Salsk061 [2.6K]

Answer:

People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.
