Answer:
Determine the parental genotypes. You can use any letter you like but select one that has a clearly different lower case, for example: Aa, Bb, Dd.
Split the alleles for each parent and add them into your Punnett square around the edges.
Work out the new possible genetic combinations inside the Punnett square.
Explanation:
Patients are encouraged to drink clear liquids (for example, water) until 2 hours before the time they are scheduled to arrive to the hospital or surgery center. remember, staying hydrated is important. However, certain procedures may require specific instructions.
I hope this answers your question.
Answer:
These neurons are located in the central nervous system (the brain and spinal cord). Afferent and efferent neurons have to work together in order to sense and respond to stimulus, but they don't directly connect. Association neurons bridge the gap to relay information between sensory and motor neurons.
Epigenetic changes are those which do not involve alterations in the DNA sequence. These are caused due to interaction of the genome with the environment.
<h3>
When are alterations epigenetic?</h3>
- Epigenetic modifications or tags include DNA methylation and histone modification.
- These changes alter DNA accessibility and chromatin structure thus regulating gene expression.
- These are the reversible, heritable changes which do not change your DNA sequence, but they can change how your body reads a DNA sequence.
- These are necessary for the normal development of organisms.
- Stable, long-term epigenetic modifications involve DNA methylation.
- Flexible, short-term changes involve histone modifications, such as methylation and acetylation.
