Q16 Fishy proteinsCod fish have two alleles for a protein that binds oxygen, called the Hb-1 and Hb-2 alleles. Fishexpressing the Hb-1 allele are found in different environments than fish expressing the Hb-2 allele.Upon bringing both groups of fish into a lab, scientists found that the Hb-1 and Hb-2 proteinsfunction differently when tested under two different temperature treatments, cold and warmtemperature. The groups of fish were similar in size, age, and sex ratios. The figure below showsthe findings from the scientist's research.highOxygen bindingperformanceΣΧΟpelowlowO TrueHb-1coldO FalseHb-2coldTemperature (°C)warmTemperature (°C)Figure 1. The oxygen-binding performance of a protein depends on which allele codes forthe protein (Hb-1 or Hb-2). The x-axis indicates the temperatures at which the protein was tested.The y-axis indicates the amount of oxygen bound to either the Hb-1 or Hb-2 protein.warmUse this information and your understanding of biology to answer questions 16-20.16. In cold water, natural selection would favor heterozygotes that expressed Hb-1 and Hb-2 at the same time.

Understanding life and its diversity has been centered on how natural selection has shaped the physical, physiological, and behavioral adaptations of animals and plants across generations ever since Darwin. The precise mechanisms by which such organismal qualities are produced and expressed over the course of an individual's lifespan by genetic, molecular, and biochemical processes have been increasingly revealed by new research. Since the 1859 publication of The Origin of Species by Charles Darwin, the sciences of biology and evolution have advanced significantly. Darwin is honored, however, for the important concepts he correctly identified, like as adaptation by natural selection and descent with modification. The former broadly refers to the fact that evolution has taken place and resulted in modern-day species being distinct from their progenitors. The evolutionary process known as natural selection explains how traits of animals and their environments complement or fit together.Natural selection affects an organism's phenotype, or its traits that interact with the environment, but any phenotype having a genetic foundation (heritable) that facilitates reproduction may spread more widely in a population. This process can eventually lead to speciation when populations specialize for specific ecological niches over time (microevolution) (the emergence of new species, macroevolution). In other words, a population's evolution depends in large part on natural selection. Here the natural selection of heterozygotes that has both Hb-1 and Hb-2 alleles express in their environment. That is Hb-1 will express high in warm environmental condition and so as high oxygen binding performance. And Hb-2 will express maximum at cold environmental condition and so as high oxygen binding performance. So the given statement is false. Because they wont express equally in cold temperature. Only the Hb-2 is expressing at high rate in cold condition. This is the physiological adaptation of the fishes in warm and cold environmental condition.
