Answer:
La frecuencia del alelo recesivo s es igual a 0.2 (opción b)
Explanation:
<u>Datos disponibles</u>:
- Plumaje gris es el fenotipo dominante
- Plumaje con manchas blancas es el fenotipo recesivo
- S es el alelo dominante para plumaje gris
- s es el alelo recesivo para plumaje manchado
- Variedad manchada representa el 4% de la población.
Si ejemplares con ala manchada y genotipo ss representan el 4% de la población, entonces los restantes 96% corresponden a ejemplares grises homocigotas dominantes SS y heterocigotas Ss. Las frecuencias fenotípicas serán:
- Plumaje gris (SS + Ss) = 96% = 0.96
- Plumaje manchado (ss) = 4% = 0.04
De acuerdo al equilibrio de Hardy-Winberg, la suma de las frecuencias alélicas equivale a 1, y la suma de las frecuencias genotípicas también equivale a 1.
- Frecuencia del alelo dominante = p
- Frecuencia del alelo recesivo = q
- Frecuencia de genotipo homocigota dominante = p²
- Frecuencia de genotipo heterocigota = 2xpxq
- Frecuencia del genotipo homocigota recesivo = q²
Entonces,
- p + q = 1
- p² + 2pq + q² = 1
Si la frecuencia genotípica del homocigota recesivo es 0.04, entonces la raíz cuadrada de ese valor es la frecuencia génica del alelo recesivo. Esto es:
A partir de la ecuación p + q = 1, podemos calcular el valor de p.
p + q = 1
p + 0.2 = 1
p = 1 - 0.2
p = 0.8
Entonces la frecuencia genotípica del homocigota dominante es p²
p² = 0.8² = 0.64
Y la frecuencia genotípica del heterocigota es
2pq = 2 x p x q = 2 x 0.8 x 0.2 = 0.32
Para corroborar esto, la suma de todas las frecuencias genotípicas debe dar uno.
0.64 + 0.32 + 0.04 = 1
The development of a rash on the genitals or the oral cavity, cold sores are also fairly common.
Carcinogens is a substance that can cause cancer. So the correct answer is B) cancer
Answer:
. Identify the process that triggers the initial surge of nitrogen excretion,
The reason for this is because of the gluconeogenesis ,(in the liver and cortex of the kidney) which make up for the reduction in glucose blood level, from rapid catabolism to glucose at the beginning of fasting, by breaking down protein to glucose in the liver. Therefore excess Nitrogen is produced as the byproducts of amino acids catabolism.
Physiologically the mammalian brain prefers the keto bodies supply from fatty acids catabolism from gluconeogenesis compare to protein. These water solube subtances cross the BBB to reach the brain the CNS substituting for glucose. Thus as more fatty acids is converted to ketobodies at faster rate, the brain gets adapted to this, and therefore catabolism of amino acids drops, hence Nitrogen concentration in the blood drops.
However, with exhaustion of Glycogen and fatty acid, catabolims of amino acids resumes. therefore, more amino acids are broken down, and Nitrogen build up in the Urine for excretion.
Explanation:
Answer: joint c: hip joint
Explanation:
- the hip joint is categorized as a ball and socket joint that allows for the body to sustain it weight and allows for large freedom of motion
- The socket, also known as the acetabulum is found in the pelvis
- The ball part of the joint is found at the top of the thighbone (femur) and connects with the socket to form the hip joint
