Question

what is the purpose of using a pedigree?
o to study the causes of traits that are acquired during an organisms life
o to understand patterns of inheritance in organisms
o to determine mating patterns in organisms
o to identify traits that are acquired during an organisms life

Explanation:

A pedigree is a diagram used in genetics. It shows the inheritance of traits across generations. It helps in understanding how traits (especially genetic disorders) are passed down. Traits acquired during an organism's life (not genetic) are not relevant here. Mating patterns are not the main focus. The key is inheritance patterns.

Answer:

to understand patterns of inheritance in organisms
