Geologists are able to make long-term predictions about earthquakes fairly well since geological events occur in bigger time spans. This can be seen by looking at the history of earthquake occurrence in a particular area where one would observe an almost uniform time span in-between occurrences.
Answer:
In a pea plant heterozygous for the color of the flower, the color exhibited by that flower the phenotype is purple.
Explanation:
According to Mendelian heritage, a dominant trait will always be present in the phenotype, even in the allelic heterozygous form, while a recessive allele will only be possible when there are two identical recessive alleles.
The presence of a dominant allele inhibits the expression of a recessive allele.
If for the character "color of the flower" the pea plant is heterozygous, it will exhibit the dominant trait in its phenotype, so its flowers will be purple.
The other options are not correct because:
- <em>White</em><em> is the recessive trait in the flower color
</em>
- <em>A mixture of purple and white</em><em> can be observed in co-dominance or incomplete dominance, non-Mendelian forms of inheritance.</em>
