Answer:
the answer is D.
Explanation:
The heritable variation is defined as the variance of the breeding values among individuals.
Answer:
A mutation in <u>DNA </u>results in a change in <u>RNA </u>that sometimes produces a <u>protein </u>with altered structure and function.
Explanation:
DNA is the hereditary material which causes gene expression in our body by producing protein. The type of protein which is produced by DNA totally depends upon the sequence of nucleotides in the DNA. But, DNA molecule does not produce protein directly. Initially it produces RNA (mRNA, tRNA, rRNA) by the process of transcription, the nucleotides in the RNA are complimentary to those in DNA. In short, the message regarding the structure and composition of the type protein to be produced by DNA is first decoded from DNA in the form of RNA. These RNA molecules then synthesize the protein as per the instructions from DNA by the process of translation.
But, in case a mutation occurs in the DNA which causes a change in it's nucleotide/nucleotides, the protein which will be produced will be different in the structure and function than the protein which was supposed to be synthesized. It happens because, a triplet of nucletiodes in the DNA and hence RNA specifies a particular type of amino acid and several amino acids are joined in a long chain to form polypeptide which ultimately forms protein. But, if any nucleotide in the triplet is changed due to mutation it may change the amino acid and if amino acid will change the protein will also get altered.
A. occurs mostly in males. Females may exhibit symptoms but rarely. Female carriers are asymptomatic (not affected). Characteristic cannot be transmitted male to male. Affected males transmit the trait to all daughters.
Its basically saying something (object) at rest is going to stay there until something moves it like an outside object.
Answer:
Explanation:
Selection breeding is use to identify individual with good physical characteristics that can be used as parent in next generation. Brown, yellow, green grasshoppers are the distinct phenotypic characteristics of an individual hence selection will be individual base. Such that brown individual will be selected, green selected seperated and yellow will also selected. The organism that shows the best fits are often been selected depending on the objects of the selection
