Answer:

The correct answer would be - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

Explanation:

It is mention that the deletion mutation and point mutation are non-overlapping or no overlapping regions in the phage genome. A crossing-over event between the regions of these two mutations would get wild-type which means there would be neither point mutation nor deletion mutation and other would be a double mutant that contains both mutation - the point mutation and the deletion mutation.

Thus, the correct answer is - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

marusya05 [52]

Answer:

Gregor Mendel

Explanation:

Gregor Mendel fue un naturalista, biogista y matemático que demostró por primera vez los principios de la herencia utilizando su trabajo sobre las plantas de guisantes.

Publicó su trabajo en "Experiments in Plant Hybridization" en el año 1866. Al controlar la polinización, Mendel pudo cruzar plantas de guisantes con diferentes formas de rasgos. En el primer conjunto de experimentos de Mendel, experimentó con solo una característica a la vez. Los resultados de este conjunto de experimentos llevaron a la primera ley de herencia de Mendel llamada ley de segregación (Bio Libretexts).
