QUÉ SIGNIFICA BACKCROSS EN INGLÉS
Retrocruzamiento
Backcrossing es un cruce de un híbrido con uno de sus padres o un individuo genéticamente similar a su padre, con el fin de lograr descendencia con una identidad genética que está más cerca de la del padre. Se utiliza en horticultura, cría de animales y en la producción de genes knockout organismos. Los híbridos retrocruzados a veces se describen con el acrónimo "BC", por ejemplo, un híbrido F1 cruzado con uno de sus padres puede denominarse un híbrido BC1, y un cruce adicional del híbrido BC1 con el mismo progenitor produce un híbrido BC2.
definición de backcross en el diccionario inglés
La primera definición de retrocruzamiento en el diccionario es aparearse con uno de sus padres. Otra definición de retrocruzamiento es la descendencia así producida. Backcross es también el acto o proceso de retrocruzamiento.
