Answer:
Heterozygous tall x homozygous short individuals
Explanation:
<em>The cross that could produce tall plant to short plant in the ratio 1:1 would be between a heterozygous tall and homozygous short individuals.</em>
Assuming the allele for tallness is represented by T and that for shortness is represented by t. TT and Tt individuals will be tall while tt individuals will be short. A cross between a heterozygous tall individual (Tt) and homozygous short individual (tt) will be such that:
Tt x tt
offspring: Tt (tall), Tt (tall), tt (short), and tt (short). <em>(see the attached image for the Punnet's square analysis)</em>
<em>The ratio of tall to short offspring = 1:1</em>
Hence, the cross is between heterozygous tall and homozygous short individuals.
CFCs are Chlorofluorocarbon substances used in refrigerants (subtances used to keep other things cold) and in aerosol products.
they are both relatively nontoxic(nonpoisonous) and nonflammabale - at least as compared to alternatives.
They are rather volatile - they are not very stable. Therefore it does not make sense to say that they are strong - the correct answer is then strength.
Dna is a polymer consisting of repeating units known as Necleotides.
Answer:
Amino acid sequences
Explanation:
The proteins perform the vast majority of functions in the cells. If a gene between a human and a mouse is evolutionarily related, it means that the function they do in the cell is quite similar in both species. This is the reason why the amino acid sequence would be the most similar.
In addition, there might be certain mutations in the DNA and therefore in the RNA between this 2 sequences that encode to the same amino acid sequence. More specifically speaking, there are more than one codon that encode to the same aminoacid. Thus, 2 different DNA/RNA sequence can give the same aminoacid sequence.
