Answer:
Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).
Explanation:
<u>Datos disponibles:</u>
- Cruce entre peces naranjas y peces grises
- 50% de la F1 son peces grises
- Naranja dominante sobre gris
Podemos nombrar el alelo dominante para color naranja <em>N</em>, y al alelo recesivo para color gris <em>n</em>.
Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.
Supongamos que uno de los parentales lleva el genotipo <em>Nn</em>, y el otro parental es <em>nn</em>.
Cruce:
Parental) Nn x nn
Gametas) N n n n
Fenotipos) Naranja Gris
Cuadro de Punnett) N n
n Nn nn
n Nn nn
F1) 2/4 = 1/2 = 50% de la progenie tendrá genotipo heterocigoto, Nn
2/4 = 1/2 = 50% de la progenie tendrá genotipo homocigota recesivo,
nn
50% de la progenie será color naranja (Nn)
50% de la progenie será color gris (nn)
Answer:
The correct answer is the option - mating factor.
Explanation:
Yeast can reproduce sexually by a signaling pathway called the mating factor pathway. Mating in yeast occurs between two haploid yeast cells. In this process, two yeast cells form a diploid cell.
In this process yeast cells secrete a signaling molecule termed as the mating factor that is used to attract them to mating cells to form a diploid cell.
Thus, the correct answer is option - mating factor.
-Plant cells are more rigid due to the cell wall.
The baglike structure that contains a clear fluid in which the developing embryo floats is called the Amnion.
<h3>
What is an Amnion?</h3>
The membrane that covers the embryos of reptiles, birds, and the mammals when first formed is called Amnion.
It contains amniotic fluid, which serves as an amniotic sac that provides a protective shield for the developing embryo. Together with the amnion, contains the
- chorion
- the yolk sac
- allantois
with different functions to protect the embryo.
The amniotic sac in humans is enclosed in the uterus while for birds, reptiles ,it is enclosed in a shell.
