Question involving the equations for Hardy Weinberg equilibrium (A^2+2Aa+a^2=1, A+a=1)
Alinara [238K]

Answer:

Frequency of dominant allele is 0.9029

Explanation:

Total number of organisms = 12,845

Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.

Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249

Frequency of recessive allele (q) = 1249/12845 = 0.0971

Frequency of dominant allele (p) = 1- q = 1-  0.0971 = 0.9029

Mitosis and cell cycle definition
Korolek [52]

Answer:Una célula pasa por cuatro etapas a lo largo de su vida, que son: el nacimiento, el crecimiento, la diferenciación y la reproducción o muerte celular.

El proceso por el cual nace una célula a partir de otra preexistente se denomina división celular. El mecanismo que da origen a un nuevo individuo, en organismos unicelulares, es decir, organismos formados por una sola célula, se produce para aumentar el tamaño de su población, mientras que en organismos pluricelulares, este proceso funciona para aumentar el número de células y el reemplazo de células que se encuentren dañadas o muertas.

El ciclo celular se define como el conjunto de transformaciones que sufren las células para generar dos células hijas.

Este ciclo está formado por tres fases: la interfase, la mitosis y la ciclo
