What was a conclusion that Mendel drew from the F2 generation of this cross?
A.
Three fourths of the F2 plants show the round seed phenotype and carry the dominant allele for roundness.
Answers
Answer:
option A
Explanation:
option A is the correct answer of this question .
plz mark my answer as brainlist plzzzz vote me also.
hope this will be helpful to you.
three fourth of f2 plant showed round seed phenotype and carry dominant allele for round ness character.
what is dominant character ?
allele can be defined as a form of a gene which can be present as a pair shows either homozygous or heterozygous phenotype of a character.
these gene can express the phenotype either dominant or recessive form. In a cross between two organism, in F2 generation the offspring's are produced shows three phenotypes homozygous dominant, recessive, heterozygous dominant.
dominant allele can suppress recessive allele.

Answers
Answer: the correct option is B.
reflections of the colors in the environment
Explanation:
This is because the environment causes different reflections of color. Fir example white light reflect colors, it will absorb all other colors except with.
The environment serves a a medium for color reflection and this has lead to different color and patterns in population. People have eye pattern and color base on their surrondings, what the surronding is made off influence the color and patterns.

1. What percentage of puppies would have the same genotype as the
parents, Ww?
Answers
Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.

Answers
Answer:
They are pollinators.
Explanation:
Bees are vital to our ecosystem because they are pollinators and due to this pollination, these bees are responsible for the presence of trees, shrubs and other small plants etc. if bees were to disappear from ecosystem Earth then the whole world is adversely affected because trees can't produces fruits and seeds so after sometime animals die due to unavailability of food. Human activities are responsible for the death of these bees because human activities causes pollution which is not good for bees. We have to make a safe place for bees and grow as many flowers as you can in order to increase their population.

A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answers
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

Explain.List ALL layers of the skin that have been damaged.What tissue repair process causes the blistering?List all of the body functions that may be disrupted by such a burn.After a few days his skin peels and the burned areas begin to heal. Matt notices that the healing areas are more susceptible to injuries due to chafing or trauma. During the next week after Matt returns to Tampa, Maria tells him that a sunburn prepares his skin for a deep tan. Maria encourages him to quickly begin tanning sessions at a local tanning salon before the effects of the burn wear off.What has happened to the skin that would cause this increased susceptibility?What would you advise him to do?

The question the scenario shows suggests, the integumentary system of Matt is affected, this system is part of the skin.
What is sunburn?A person having lesser melanin content in their skin has the risk of developing redness, swelling, and pain in the skin indicative of cellular damage caused by excessive sun UV radiation, this is known as sunburn.
Matt received a second-degree sunburn, which affects the dermal and epidermal layers of the skin. The inflammatory stage, proliferation stage, and matrix remodeling are the tissue repair process.
The skin is the first line of defence and acts as a barrier, after this injury affect this line of defence is affected causing entry of pathogens inside the body.
In absence of the epidermis, when the dermis is exposed, easily bruises and injury occur since blood vessels are exposed to the skin's surface.
Therefore, excessive exposure to the UV light creates deep tan signs.
