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 order would be - V, II, IV, I, III
Explanation:
Mitosis is one of the two types of cell division that occurs in an organism however they both take place in different types of cells. Mitosis is the process in which the genetic material or specifically chromosomes divide into two nuclei that are genetically identical to the parent cell. They also have a similar number of chromosomes.
Mitosis division is completed in the four stages followed by cytokinesis in order which are prophase, metaphase, anaphase, telophase, and division of cell or cytokinesis.
Thus, the correct answer is - V, II, IV, I, III.
It is important to ask about the reactions caused by an insect bite because this will allow you to act quickly if there are health effects.
<h3>What is an insect sting?</h3>
The insect sting is the way in which insects defend themselves when they feel attacked by other organisms. Insects generally have stingers or spikes on their bodies to defend themselves against predators.
<h3>Why is it important to be aware of the effects of a sting?</h3>
When a person suffers a sting, it is necessary to report all the symptoms that they experience because some insects have substances that affect the body and can cause allergic reactions that put the health and life of the individual at risk.
