The only way to obtain the correct phenotype, but not the correct genotype in a genetic cross is when ignoring the genotype of the parental lines. The genotype of a trait is always a consequence of random segregation.
<h3>Alleles, random segregation and phenotypes </h3>
An allele is a gene variant for a given <em>locus</em>, in a diploid organism, two alleles are inherited (one from each parent).
Random segregation refers to the independent way in which alleles separate during the formation of gametes.
Random segregation determines the genotype in a genetic cross, but it is not possible to determine if an allele is associated with a given phenotype if we don't know the genotypes of the parental lines.

Answer:
A. Fish need light to see their food
Explanation:
B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.
C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)
D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.
A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

Explanation:
Answer:c) glucose
Explanation: The complete balanced chemical equation is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
The equation above represents cellular respiration. During respiration, one molecule of glucose (C6H12O6) is broken down in the presence of six molecules of oxygen (O2) to produce six molecules of carbon dioxide (6CO2), six molecules of water (6H2O) and energy (ATP).
