how both genetic and environmental factors can affect paint color variation in california rabbits
Answer:
Coat color in rabbits is inherited as a series of multiple alleles.
Explanation:
This means that there can be more than just 2 alleles for a single gene. In the case of coat color in rabbits, there are four alleles, and each one is expressed with a different phenotype.
The genetic factors that can affect paint color variation in California rabbits are based on the several different genes that are inherited from their parents. It includes color base, color density, pattern, an extension of dark pigment, spotting, silvering, etc.
What are the genes that are responsible for color variations?The genes that are responsible for color variations are as follows:
Gene A controls the pattern of the coat.Gene B controls the base of coat color.Gene D controls the density of the coat color.Apart from these direct genes, several other genes are also responsible for causing variations in paint color in Rabit. The effect of environmental factors remains the same for every species regardless of competition, and other limited resources. These environmental factors govern the alteration gradually over a long period of time to stimulate some observable responses in the organisms.
Therefore, the genetic and environmental factors that can affect paint color variation in California rabbits are well described above.

what gender tachycardia affects most?
A female mosquito can produce 50-500 offspring in a two-week period of time. This rapid reproduction can also result in fast
evolution for this small insect species. For example, pesticide resistance occurs rapidly in insects, including mosquitos. Insecticides
that were once effective at eradicating mosquito populations are no longer effective. Which component of natural selection is
Likely playing a role in this rapid evolution for mosquitos?
A)
Mosquitoes pass only advantageous traits on to their offspring during
reproduction. This ensures increased survival and reproduction.
B)
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
Mosquitoes that learn to avoid pesticide exposure can pass that
information on to offspring. This increases the survival of those offspring
as well.
D)
Mosquitos have the ability to detect areas with high pesticide loads and
can avoid those areas. This allows mosquitos to survive and reproduce with
more success.
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
What are mosquitoes?Mosquitoes are ectoparasites, which live on the blood of different animals.
They suck blood from the skin of animals and leave red spots, which are itchy.
Mosquitoes lay their eggs in water and live in dirty, moist, dark places.
They are also responsible to cause malaria in humans.

4. Describe what occurs during the process of seed development.
5. Based on your knowledge of flowers, why do you think most flowers are bright in color?
The plant is made up of root and shoot structures that contain parts that enable the plant to grow and manufacture its food.
The structure and function of plantsThe structure of plants is made up of tissues such as:
phloemstomaxylemguard cellsdermalground andvascular.The three characteristics that all species being to the plant kingdom have in common are:
They are non-motile,They make their food hence are called autographs; andTheir cell walls are made sturdy by a material called celluloseThe tropical plants have more stomata than the desert plants. This helps the desert plants to reduce water loss.
Some defects occur when there is damage to the vascular tissues such as the xylem( plant will not be able to transport water from the soil through roots to leaves) and phloem (nutrients produced during photosynthesis will not be able to reach every part of the plant body).
The dermal tissue of plants and the human skin performs protective roles to the underlying tissue organs.
A plant won't be able to survive because it won't absorb water and nutrients from the soil and transport it upwards to all the parts of the plant.
Flowering reproduction in plants takes place through the following steps:
Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.Flowers benefit other organisms in our environment by creating more carbon dioxide-absorbing and oxygen-radiating plants.
The flowers contain male reproductive organs called stamens and female reproductive organs called pistils.
The process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.
Most flowers are bright in color because they are like advertisement signs for pollinators.
