Hi! :)
Make a = q, aa (homozygous recessive) = q^2,
A = p, AA (homozygous dominant) = p^2, and
2pq = heterozygous
This was derived from p + q = 1
Therefore all a in pop (q) = 20% = .20
And all A in pop (p) = 80% = .80
Since the disease is homozygous recessive (affected), then aa = qq or q×q = q^2
q^2 = (.20)^2 = .040 = 4%
Answer: 4%
Answer:
50%
Explanation:
La información que tenemos es:
Un hombre homocigoto (ee) que carece la posibilidad de enrollar su lengua.
Una mujer heterocigota (Ee). Al tener dos copias distintas de este gen, la mujer puede enrollar su lengua ya que este es un gen dominante (E) sobre el gen recesivo (e) que impide este movimiento.
Si hacemos un Cuadro de Punnett veremos que la capacidad de enrollar la lengua en los descendientes de esta pareja tiene una probabilidad fenotípica del 50% ya que hay un 50% de probabilidades de que su descendencia tenga un genotipo Ee y otro 50% de que sea ee, lo cual se expresa en una probabilidad fenotípica, es decir lo que se puede apreciar visiblemente como resultado de la interacción del genotipo y el ambiente, de con un 50% de poder enrollar la lengua.

D.) Bioaccumulation is your answer.......
Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
