The mechanism that breaks the linkage between linked genes is

Biology
1 answer:
gregori [183]3 years ago
8 0

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.

Random distribution is also known as predictable spacing. <br><br> true ot false?
Marat540 [252]

Random distribution is not the same predictable spacing. Hence, the correct answer would be False

In actual fact, random distribution can be said to be the direct opposite of predictable spacing.

For example, when a group of numbers is randomly distributed, each number has an equal chance of being located within the distribution. In predictable spacing, each number would have a predefined probability or an unequal chance of being located.

konstantin123 [22]

Answer:

The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.

Explanation:

The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.

Why does the mass of a substance remain the same after a chemical reaction
11111nata11111 [884]

Answer:

Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange, and re-bond in a different arrangement to form the products.
