The discarded theory of blending inheritance most closely resembles what inheritance
pochemuha

The discarded theory of blending inheritance most closely resembles incomplete dominance.

<h3>What is blending inheritance?</h3>
  • An antiquated biological notion from the 19th century is the concept of blending inheritance.
  • According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
  • According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
  • As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
  • Offspring thus combines the traits of both parents.
  • Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
  • The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
  • Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

What organelle does the mRNA strand go to so protein synthesis can start?
sergiy2304 [10]

Answer:

The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.

Explanation:

In protein synthesis, the first step is to <em>synthesize messenger RNA</em>, mRNA. The coping process of the DNA section for the desired protein is called <u><em>transcription</em></u>, and it happens in the <em>nucleus</em>. After that, it occurs <em><u>translation</u></em>, when the formed <em>mRNA moves to the </em><em>cytoplasm</em> through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of <em>protein and ribosomal RNA</em> and can be found in the r<em>ough endoplasmic reticulum</em> or floating in the <em>cytosol</em>. They read the mRNA code and add the correct amino acid using <em>transference RNA</em> to build the protein. mARN has a <em>start and end codon</em> that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is <em>folding</em> to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.
