can someone answer this pls??

Answers

Answer:

75% brown, 25% white

Explanation:

This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).

According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.

Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:

¾ or 75% brown and ¼ or 25% white

Glycolysis, or the breakdown of glucose, is a process used by almost all organisms as a way to release energy stored within glucose molecules. This energy can then be stored in cells as ATP, which powers cell processes when needed. What does this show, in terms of the evolutionary history of cells using glycolysis?

Answers

Answer:

It was one of the earliest metabolic pathways.

Explanation:

The evolutionary history of cells using glycolysis shows that It was one of the earliest metabolic pathways which is used by nearly all of the organisms on earth for the production of energy for the survival, growth and development. The first organisms used this pathway for the generation of energy and with the passage of time, new pathways are also formed as the organism evolved so we can conclude that glycolysis is the first pathway used by the earliest organisms.
