1/14
  • Chi Square Test
    Statistical method comparing observed and expected values to assess the likelihood of genetic linkage.
  • Gene Linkage
    Physical proximity of genes on a chromosome, affecting their tendency to be inherited together.
  • Heterozygous Organism
    Individual possessing two different alleles for a specific gene, crucial for linkage analysis crosses.
  • Parental Type
    Offspring displaying the same trait combinations as the original parents in a genetic cross.
  • Recombinant Type
    Offspring exhibiting new trait combinations not found in the parental generation.
  • Recombination Frequency
    Proportion of recombinant offspring, indicating the likelihood of crossover between genes.
  • Null Hypothesis
    Assumption that observed and expected results are not significantly different, implying no linkage.
  • Degrees of Freedom
    Value calculated as the number of categories minus one, used to interpret statistical significance.
  • P Value
    Probability indicating the likelihood that observed differences are due to chance, guiding hypothesis acceptance.
  • Critical Value
    Threshold from statistical tables used to determine if the test statistic is significant.
  • Observed Value
    Actual data collected from an experiment, such as the number of parental or recombinant offspring.
  • Expected Value
    Predicted outcome based on the null hypothesis, serving as a comparison for observed results.
  • Statistical Significance
    Measure indicating whether experimental results are unlikely to have occurred by random chance.
  • Confidence Level
    Percentage expressing certainty in a statistical conclusion, such as 95% confidence in hypothesis testing.
