LO TENIA GUARDADO ESPERO QUE LES SIRVA TEMA ES MEIOSIS

1. Meiosis

2. ¿ Qué es Meiosis ?
✖
La meiosis es un proceso de división celular a través del cual a partir de
una célula diploide se producen cuatro células haploides.
2
Las células haploides son aquellas que
contienen un solo juego de cromosomas. Los
gametos o las células sexuales (es decir, los
óvulos y los espermatozoides) son células
haploides. Así, pues, el objetivo de la meiosis
es generar células sexuales

3. Fases de la meiosis
✖La meiosis se
produce
mediante un
proceso de
división celular
de dos etapas:
meiosis I y
meiosis II.

4. Meiosis I
También conocida como fase reductiva, es la etapa donde los pares de
células homólogas se separan, dando como resultado que el material
genético de las células hijas sea la mitad del de las células progenitoras. Es
esto lo que genera diversidad genética. Se subdivide en cuatro fases:
4
•Profase I: Los cromosomas se condensan y forman pares. Se
produce el entrecruzamiento y la recombinación genética, que
permite el intercambio de partes de cadenas de ADN que dan
lugar a un nuevo material genético.

5. 5
Metafase I: los pares homólogos se alinean en la
placa metafásica para que se produzca la
separación.
Anafase I: los cromosomas se separan moviéndose a
extremos opuestos de las células, mientras que las
cromátidas hermanas permanecen juntas.
Telofase I: se forman las células haploides. Cada
cromosoma tendrá dos cromátidas hermanas, que ya no
serán iguales entre sí.

6. Meiosis II
También conocida como fase reductiva, es la etapa donde los pares de
células homólogas se separan, dando como resultado que el material
genético de las células hijas sea la mitad del de las células progenitoras. Es
esto lo que genera diversidad genética. Se subdivide en cuatro fases:

•Profase I: Los cromosomas se condensan y forman pares. Se
produce el entrecruzamiento y la recombinación genética, que
permite el intercambio de partes de cadenas de ADN que dan
lugar a un nuevo material genético.

Yellow
Is the color of
gold, butter and
ripe lemons. In
the spectrum of
visible light,
yellow is found
between green
and orange.
Blue
Is the colour of
the clear sky and
the deep sea. It is
located between
violet and green
on the optical
spectrum.
Red
Is the color of
blood, and
because of this it
has historically
been associated
with sacrifice,
danger and
courage.

A complex idea can be conveyed with just a single still image,
namely making it possible to absorb large amounts of data quickly.

25. SlidesCarnival icons are
editable shapes.
This means that you can:
● Resize them
without losing
quality.
● Change fill color
and opacity.
Isn’t that nice? :)

27. Now you can use any emoji as an icon!
And of course it resizes without losing quality and you can
change the color.
