Mendel also wondered if the inheritance of one trait affected the inheritance
svet-max [94.6K]

Answer:

A. dihybrid crosses

Explanation:

A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.

How is DNA copied?
Sedaia [141]

Answer:

The DNA is copied by B: The sense strand of DNA is used as a template to create both strands of the new double helix.

Explanation:

Ok, the DNA is "copied" in the tanscription process. The transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Also, the DNA safely stores genetic material.

During the process of transcription a single strand of RNA is synthesized using a double stranded DNA molecule as a template.  The two strands of the DNA molecule are separated from one another, exposing the nitrogenous bases. Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.
