The mechanism that breaks the linkage between linked genes is
gregori [183]

Answer:

Crossing over

Explanation:

Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.

Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.

Protein recommendations are the daily dietary protein requirements for an individual based on that individual's weight.

<h3>What was the dietary protein requirement?</h3>

For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight. For instance, 60 grams of protein should be consumed daily by a person who weighs 165 pounds, or 75 kilograms.

Christine has already ingested half of the 40 grams of dietary protein that her doctor recommended. This indicated that she had already ingested roughly 20 grams of the recommended dietary protein and needed an extra source of protein to meet her daily needs. Christie must therefore have four more servings of snacks to complete her daily protein requirements.
