narvez 5. Everyone in Dobby's family has a long nose and they brag that they are from a purebred line. Viola has a stubby nose. Draw a punnett square to determine the possible types of noses their children could have had. (Use the genotypes from #2) a. List the possible genotypes and phenotypes for their children. b. What are the chances of a child with a long nose? out of or % c. What are the chances of a child with a stubby nose? out of st or__% d. Would their children be considered purebred like Dobby? Explain:​

Answers

Answer 1

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

---------------------------------

Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.

I advise you to check on them and see which one matches the genotype from #2.

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

SCENARIO 1  ⇒ long nose is the dominant trait

Let us say that

L is the dominant allele and codes for long nosel is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

LL and Ll ⇒ long nosell ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

Cross 1

Parentals)    LL   x    ll

Gametes)  L    L     l    l

Punnett square)    L       L

                      l      Ll      Ll

                      l      Ll      Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

     Phenotype ⇒ 100% long-nosed

There is 100% chances for a child to have a long noseThere is 0% chances for a child to have a stubby noseThese children are not purebred

                                             **********

SCENARIO 2  ⇒ Stubby nose is the dominant trait

Let us say that

S is the dominant allele and codes for stubby noses is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

SS and Ss ⇒ stubby nosess ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

Cross 1 : Violet is h0m0zyg0us dominant SS

Parentals)    SS   x    ss

Gametes)  S    S     s    s

Punnett square)   S       S

                      s     Ss     Ss

                      s     Ss     Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

     Phenotype ⇒ 100% stubby-nosed

There is 100% chances for a child to have a stubby noseThere is 0% chances for a child to have a long noseThese children are not purebred

Cross 2: Violet is heter0zyg0us, Ss

Parentals)    Ss   x    ss

Gametes)  S    s     s    s

Punnett square)   S       s

                      s     Ss     ss

                      s     Ss     ss

F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss

     Phenotype ⇒ 50% stubby-nosed and 50% long-nosed

There is 50% chances for a child to have a stubby noseThere is 50% chances for a child to have a long noseThese children are not purebred

The diagram shows the reproductive system of a plant.



Which of the following best describes the interaction that occurs between a plant's reproductive parts during self-fertilization?


Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.


Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.


Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

Answers

Pollen is released from the anther and is transferred to the stigma. It's the 3 rd answer that is correct

The correct answer is pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

This option correctly defines the interaction that occurs between a plant's reproductive parts during self-fertilization as it explains the pollination process and fertilization, when pollen grains are released then are transferred to the stigma the pollen tube is there that reaches ovule and the sperms fertilize an egg.

What is pollination?

Transfer of pollen from anther to the stigma of plants. Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

Thus it is clear that the answer explained above is correct describes the interaction that occurs between a plant's reproductive parts during self-fertilization.

What is Supernova?

A star that has reached the end of its life and bursts in a bright flash of light is what is known as a supernova.

Supernovae have the ability to briefly outshine entire galaxies and emit more energy in a single second than the sun does in its entire lifetime. Additionally, they are the universe's main supplier of heavy materials. Supernovae are "the greatest explosion that occurs in space," according to NASA.

Supernovae were noted by numerous cultures before the telescope was created in the 17th century. According to NASA's records, this "guest star" was visible in the sky for eight months.

If an invasive species emigrated from a continent to a small island near the continent, what would most likely occur on the island

Answers

Answer:

Organisms on the island would migrate to a larger island.

Invasive species can cause extinctions, reduce biodiversity, compete for resources, and modify environments.

What is an invasive species?

An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.

Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.

Why do sunspots appear as dark spots on the surface of the Sun?​

Answers

Answer:

I think it is because the sun has released energy and looses light in that area because of it.

Explanation:

Why do sunspots appear as dark spots on the surface of the Sun?

Answer: Sunspots are "dark" because they are cooler than their surroundings. ... Sunspots have a lighter outer section called the penumbra, and a darker central region named the umbra. Sunspots are caused by disturbances in the Sun's magnetic field welling up to the photosphere, the Sun's visible "surface".

Facts about the sun: The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light, ultraviolet light, and infrared radiation. It is by far the most important source of energy for life on Earth.
