Explanation:
If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).
To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.
It codes for all the processes within the cells and contains the DNA.
Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
Answer:
C. habituation trials continue after the response has disappeared.
Explanation:
habituation involves the complete elimination of a particular response (i.e, zero frequency of occurrence). If the stimulus cintinues to be presented for an additional number of trials, then, although no further changes occur, the response will exhibit lower levels of recovery (e.g, spontaneous recovery is reduced) as if the response would have fallen below a zero frequency.
