I think the answer could be B
Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.
Answer: However, most non-canonical genetic codes are inferred from DNA sequence alone, or occasionally DNA sequences and corresponding tRNAs. Because the code governs the translation of nucleotide to amino acid sequences, a code can in principle only be confirmed when both the gene and protein sequences are known
Explanation :DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... Every living organism uses that same system. Basically, every three pieces of DNA becomes one amino acid.
Answer:
The correct answer is option c.
Explanation:
Starting from the initial primates to the hominids, and eventually, to Homo sapiens, the brain of humans has grown spontaneously. The volume of the brain has increased with the evolution of humans, that is, starting from about 600 cubic centimeters in Homo habilis to 1600 cubic centimeters in Homo neanderthalensis. The Homo neanderthalensis was the hominid with the largest size of the brain, that is, with the maximum cranial capacity. The enhancement in the size of the brain ceased with neanderthals. After that the shrinking of the brain size took place.
