Question

1 multiple choice 20 points what is a punnett square used for? predicting the probability of inheritance in offspring. tracing the line of inheritance of a particular trait, usually over several generations. sequencing the genome of an individual. viewing the layout of an individuals chromosomes.

Explanation:

• A Punnett square is a tool in genetics (a subfield of Biology) that shows the possible genetic combinations from parental alleles. It calculates the probability of offspring inheriting certain traits.
• Tracing inheritance over generations is done by pedigree charts, not Punnett squares.
• Genome sequencing is a different molecular technique, and viewing chromosomes (karyotyping) is not related to Punnett squares.

Answer:

A. Predicting the probability of inheritance in offspring.
