Question

what did mendel use to predict the patterns of inheritance in his pea plants? dna testing statistical analysis a computer a microscope

Explanation:

Mendel conducted experiments with pea plants. He counted the offspring with different traits in each generation. By analyzing these numbers (which is statistical analysis), he was able to predict the patterns of inheritance. DNA testing was not available in Mendel's time (he lived in the 19th century, and DNA structure was discovered in the 20th century). Computers were also not invented then. A microscope would not help in predicting inheritance patterns as it is used for visualizing small structures, not for analyzing inheritance ratios.

Answer:

statistical analysis
