Es la formación de los gametos o células sexuales en los seres vivos.

La gametogénesis es el proceso mediante el cual se forman los gametos en los seres vivos, diferenciándose en ovogénesis y espermatogénesis. La ovogénesis se inicia en el periodo prenatal cuando las oogonias se dividen mitóticamente y forman el ovocito primario.

Name the character


Type in the name of the character whose change throughout the story you are going to analyze.

Example: Nick Carraway.

OVOGENESIS

Character's behavior

Think of the character's behavior at the beginning of the story and look for the way it changed throughout the story.

OVOCITO SECUNDARIO- Su núcleo comienza la segunda división meiótica hasta la metafase

Change in behavior

In what way did the character change the other behavior(s) you mentioned? Type in a relevant quote.

Example:
'You said a bad driver was only safe until she met another bad driver? Well, I met another bad driver, didn't I? [...]
I thought you were rather an honest, straightforward person. I thought it was your secret pride.'

La maduración del ovocito termina con la degeneración de los dos cuerpos polares

forma el segundo cuerpo polar

Si es fecundado finaliza la segunda división meiotica

OVOCITOS PRIMARIOS- Completa la división meiótica y da lugar a un ovocito secundario y un cuerpo polar

Change in behavior

How did the character change the first behavior you mentioned? Type in a quote to prove your statement.

Example: Nick assumes the whole responsibility for Gatsby's funeral arrangements, 'with that intense personal interest to which every one has some vague right at the end.'

OVOCITO PRIMARIO- encerrado en un folículo, constituyen el "folículo primordial"

Initial behavior

What is the character's behavior at the beginning of the story? Type in a relevant quote for your statement.

Example: Nick seems to be an honest person, calling himself 'one of the few honest people that I have ever known'.

Pero no finaliza la profase

Comienzan a dividirse antes del nacimiento del feto por meiosis

OOGONIA- se divide mitoticamente, se agrandan y forman ovocito primario

Initial behavior

How does the character act at the beginning of the story? Type in a relevant quote for your statement.

Example: Nick shows his immature side as he leaves to New York in order to avoid 'being rumored into marriage' with his girlfriend.

ESPERMATOGENESIS

Character's feelings

Focus on the way the character's feelings are presented at the beginning and at the end of the story, while explaining why they have changed.

PERIODO POSNATAL
ESPERMATOCITO SECUNDARIO- Entra en meiosis II y se transforma en espermatide.

se produce la ESPERMIOGENESIS y se transforma en "espermatozoide"

ESPERMATOCITO PRIMARIO- Entra en mitosis y da el "espermatocito secundario"
ESPERMATOGONIA B- Por mitosis dan origen a los "espermatocitos primarios"
ESPERMATOGONIAS- por mitosis da origen a "espermatogonias B"

Change of feelings

How did the character change the belief you mentioned?

Type in a relevant quote for his change.

Example: 'Winter night and the real snow, our snow(...)We drew in deep breaths of it . . . unutterably aware of our identity with this country for one strange hour before we melted indistinguishably into it again. That's my middle-west.' - Nick on the purity and integrity of Midwest.

PERIODO PRENATAL
ESPERMATOGONIAS A- proliferan las células germinativas por mitosis

Initial feelings


How does the character feel about a certain subject at the beginning of the story? Type in a relevant quote to support your statement.

Example: "Reserving judgements is a matter of infinite hope."

se mantienen inactivas hasta la pubertad

GAMETOGENESIS
