Final answer:
Transmission genetics is the field that studies how genes are passed on from parents to offspring and involves the chromosomal basis of inheritance following Mendelian principles.
Step-by-step explanation:
The field of genetics that focuses on how genes are passed on from parents to offspring is known as transmission genetics. This area is concerned with the pattern of passage of genes, which is also known as the chromosomal basis of inheritance. Mendelian genetics, as proposed by Gregor Mendel, laid the foundation for our understanding of how traits are inherited. Transmission genetics examines how alleles for specific genes are inherited according to Mendel's principles.
