False

Ethyl alcohol is formed only during alcoholic fermentation and in lactic acid fermentation lactic acid is formed
There will be no dwarf pea plants in the first generation, because T is the dominant gene
Explanation:
Karyotyping is <u>a test to examine chromosomes in a sample of cells</u>. This test can help identify genetic problems as the cause of a disorder or disease.
When scientists measure, they use the metric system.
Answer:
C
Explanation:
If the population is in equilibrium, the allele frequencies will be constant.
There is nothing about the heritability of dominant or recessive alleles that make dominant ones any more likely by nature. This rules out choices A and B.
Genetic drift mentioned in D refers to alleles leaving a population. Nothing like this was mentioned in the question, so count that answer out.
C is the only remaining answer by process of elimination. It is also the most logical choice. Directional selection refers to a process of natural selection wherein extreme phenotypes (notched leaves, or non-notched leaves) are favored. In this case, there may be some external pressure causing notched leaf plants to be more evolutionarily fit, meaning that they survive long enough to reproduce more and increase allele frequency of the dominant allele.
