Answer:
The F2 generation can be explained because the alleles for flower colour and pollen shape are linked.
Explanation:
<em>When two alleles are linked on the same chromosome, there is a high tendency for the alleles to be inherited together. Consequently, the frequency of the alleles recombining in subsequent generations is low.</em>
This is what Bateson and Punnet observed. There exist a linkage between P and L alleles and also p and l alleles, thereby increasing their frequencies of occurring together and decreasing the frequency of their recombination.
Thus, the F2 generation observed by Bateson and Punnet is due to linkage of alleles.
Answer:
No heart, no blood and no circulation, but plants do need a transport system to move food, water and minerals around. They use two different systems – xylem moves water and solutes from the roots to the leaves – phloem moves food substances from leaves to the rest of the plant
True, reddish-yellowish color on pH paper shows acidity
Answer:B. is false
Explanation:
Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription. ... Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA.
Answer:
the outermost layer of Earth's lithosphere
Explanation:
the outermost layer of Earth's lithosphere that makes up the planet's continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates. The continental crust forms nearly all of Earth's land surface.
