Question

Do all offspring from the same parents inherit identical variations of a trait

Answer 1

No, children of the same parents do not all have the same variations of a trait. This is so because each child receives a certain gene combination from each of their parents, and features are frequently controlled by the interaction of several genes. Furthermore, environmental influences can still affect how a feature manifests in two offspring even if they share the same gene combination for that trait.

Answer 2

Yes


When chromosome pairs randomly align along the metaphase plate during meiosis, each member of the chromosome pair contains one allele for every gene. Each gamete will receive one copy of each chromosome and one allele for every gene.
