What is strong evidence used to support the relatedness between organisms of the same species?

Genetic similarity and DNA sequencing.

What are chromosomes, genes, alleles, karyotypes?

Chromosomes are structures that carry genetic information, genes are segments of DNA that code for traits, alleles are variations of genes, and karyotypes are the complete set of chromosomes in an organism.

How do you figure out who the parents of an animal are using alleles?

By comparing the alleles of the offspring to those of potential parents.

What are two benefits of living in a group for animals?

Increased hunting success and enhanced protection from predators.

What are some downsides of living in a group?

Competition for resources and increased risk of disease transmission.

How does gel electrophoresis work?

It separates DNA fragments based on size by applying an electric field to a gel.

How do you use gel electrophoresis to find parentage?

By comparing the DNA profiles of the offspring to those of the parents to see if the alleles match.

What are the basic functions of chromosomes in heredity?

They store and transmit genetic information.

What role do alleles play in inheritance?

They determine the variation in traits passed from parents to offspring.

What is the significance of karyotypes in genetics?

They can reveal chromosomal abnormalities and help determine the sex of an individual.
