Answer:
D) metaphase
Explanation:
Mitosis is a type of cell division in which the cell divides its replicated chromosome in equal amount in two daughter cells. Mitosis takes place in four phases: Prophase, Metaphase, Anaphase and Telophase.
Metaphase is the stage of the cell division during which the chromosome is present in the highly condensed form present in the centre of the cell. The chromosomes are aligned at the equator of the cell.
Thus, metaphase is the correct answer.
Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
Answers:
el pelo rizado en los perros domina sobre el pelo liso. una pareja de pelo rizado tuvo un cachorro de pelo tambien rizado y del que se quiere saber si es heterocigótico ¿ con que tipo de hembras tendrá que cruzarse?

El cachorro puede ser "Aa" o "AA". Se quiere saber si es "Aa". Para eso, tendría que cruzarse o con un homocigoto recesivo (aa), puesto que es el que da un 50% de probabilidades de que los hijos sean de pelo rizado.
Entonces, si se cruza con un homocigoto recesivo, la probabilidad de la descendencia debería ser 2 cachorros de pelo rizado y 2 cachorros de pelo liso.
La hembra tendría que ser de pelo liso para asegurarse de que sea homocigoto recesivo.
Si todos los cachorros salen con el pelo rizado, entonces el padre es homocigoto "AA".
Si al menos uno sale con el pelo liso, entonces el padre es heterocigoto "Aa"
