How is the blending theory of inheritance useful in genetics?
makkiz [27]

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

<h3>What is blending inheritance?</h3>

Blending inheritance is an outmoded biological theory from the nineteenth century. According to the theory, children inherit any characteristic as the average of their parents' values for that characteristic.

As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance.

Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

Thus, this can be the importance of blending inheritance.

Alika [10]

Answer:

Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor

Explanation:

When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
