TRUE OR FALSE 1. The gametic incompatibility is an example of an extrinsic reproductive barrier between species 2. Reinforcement model requires a penalty for hybridization between populations or species. For example, hybrids would show lower survival rates. 3. Polyploidy is the differential investment in gametes by different sexes. For example, 1 sex invests more energy in producing sperm or eggs 4. Analogous traits are those that are similar because of common ancestry, and homologous traits are those that are similar because of convergent evolution 5. Gametic incompatibility is an example of an extrinsic reproductive barrier between species

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
