En un cruce entre peces naranjas y peces grises se obtiene una generación (f1) de 50% peces grises . Realice el cruce y explique
Ilya [14]

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)

which of the following individuals is most likely to allow a recessive lethal gene to be kept in a population over several gener
IRINA_888 [86]
The birth and reproduction of Carrier(Heterozygous) organisms, (i.e) heterozygous individuals that have a dominant allele masking the effects of the recessive 'lethal gene.' However even though the gene is masked, it is still there. Therefore, if the heterozygous individual is to reproduce with another heterozygous (carrier) organism there is a higher chance that their offspring will have the active form of the 'lethal gene' causing the death of the offspring.

cestrela7 [59]
<span>The research shows that the relationship between estrogen and verbal tasks is negative while it is positively correlated with spatial tasks. This correlation shows that, like in other animal studies, there could be some sort of organizing of the brain that goes on related to the level of sex hormones in the body.</span>
