When building a nest, a female Fisher's lovebird cuts long strips of vegetation and carries them to the nest site one at a time
il63 [147K]

Answer: The observation clearly shows that certain behaviors are genetically controlled

Explanation:

From the observation, the Fishers bird uses long strip while the Peach-faced uses short strips and there offspring uses intermediate. It is an indication that the behavior of the length of strips cut by the bird is under genetic control and it can also be concluded that both the Fisher bird or Peach-face bird does not have complete dominance over length of strips cut for nest making.

In a study of genetic variation of the Graceland gene, a researcher finds that there are two alleles in a population. In a large
Licemer1 [7]

Answer:

Option 1, No. The highest frequency of heterozygotes under Hardy-Weinberg equilibrium is 0.5

Explanation:

As per Hardy Weinberg’s equilibrium principle, the maximum frequency of heterozytotic individuals occur only when half of the population is dominant and recessive homozygous.  

In other way when the sum of frequency of dominant and recessive species is equal to 0.5, only then the frequency of heterozygotes is maximum which in any case would not be higher than 0.5.  

Hence, option 1 is correct

What is translation? What does it make? Where does it occur?
tigry1 [53]

Answer:

I hoped this helped

Explanation:

Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA).Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.Lastly, termination occurs when the ribosome reaches a stop codon (UAA, UAG, and UGA). Since there are no tRNA molecules that can recognize these codons, the ribosome recognizes that translation is complete. The new protein is then released, and the translation complex comes apart.
