In the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
Gnesinka [82]

Answer:

The correct answer is : option B.

Explanation:

Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.

Hardy Weinberg equation is :

            P²+2pq+q² = 1

Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa)  as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).  

Thus, the correct answer is : option B.

maxonik [38]

Answer:

The interaction between the sloths and the leaves they eat is an example of a<u> predator-prey</u> relationship. In this example, sloths are <u>herbivores</u> that acquire their nutrients and energy from the<u> plants</u> they eat. The colors of coral snakes provide these animals with <u>mimicry</u> to avoid predation. Specifically, their coloration helps them <u>advertise their toxicity.</u> The interaction between the hosts and the ticks that live on them can be characterized as <u>parasitism</u>, because <u>one species feeds on the other</u>.

Explanation:

Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.

Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.

Please help me I don’t understand it.
Irina18 [472]

Answer:

1) bay - 0%

  cream - 0%

  buckskin - 100%

2) cream - 25%

    bay - 25%

   buckskin - 50%

3) co-dominance

Explanation:

Ok so a run down on Punnett Squares,  all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture.  Now, co-dominance, this basically means that there is no dominant allele.  For example, imagine a white flower (W) and a red flower (R).  If these two plants were to breed, you would get a pink flower (WR).  This means the red allele and the white allele are both co-dominant.  It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink.  This is also how you get an AB blood type.

I hope this helps!
