Final answer:
The frequency of the h/h phenotype per million cannot be determined without specific data on the gene and its prevalence in the population. The student's question appears to relate to population genetics, which deals with allele frequencies and inheritance patterns. The Hardy-Weinberg principle could be used if allele frequencies were known.
Step-by-step explanation:
The frequency of the h/h phenotype per million in the human population is not explicitly given in the information provided. To determine the frequency of a recessive phenotype like the h/h genotype, one would typically use the Hardy-Weinberg principle, which relates allele frequencies to genotype frequencies in a population at equilibrium. However, the answer to the student's question would depend on the specific gene in question and the frequency of the recessive allele in the population. Typically, such data would come from epidemiological studies or genetic surveys. If we had a homozygous recessive frequency for a particular affliction or characteristic as 0.37 (37%) in a population of 1000 organisms, the frequency per million would be much higher than the options provided (A: 1 in 1 million, B: 1 in 100,000, C: 1 in 10,000, or D: 1 in 1,000). Hence, to provide a precise answer, additional specific data regarding the h/h phenotype is required.
In population genetics, the allele frequency (or gene frequency) is crucial for understanding evolutionary changes and predicting the occurrence of certain phenotypes. With the ABO blood type system as an example, the frequency of an allele like IA can be calculated based on the proportion of individuals in a population with that genotype. If the population is large and the sample size is sufficient, this can give us useful predictions, although the influence of chance can still affect the actual observed ratios in smaller populations or families.
