 If Darwin had been aware of genes and their typical mode of transmission to subsequent generations, with which statement would he most likely have been in agreement?

#Unit 11. Evolution and Behavior

  1. If natural selection can change gene frequency in a population over generations, given enough time and genetic diversity, then natural selection can cause sufficient genetic change to produce new species from old ones.

  2. If an organism's somatic cell genes change during its lifetime, making it more fit, then it will be able to pass these genes on to its offspring.

  3. If an organism acquires new genes by engulfing, or being infected by, another organism, then a new genetic species will result.

  4. A single mutation in a single gene in a single gamete, if inherited by future generations, will produce a new species.

#Unit 5. Developmental Biology

Programmed cell death, or apoptosis, is an essential part of animal development. In the nematode, with its invariant cell lineage, particular cell lineages or particular cells within specific lineages are destined to end in programmed cell death, and it was this feature that allowed the identification of the process and the analysis of its genetic control.

Which of the following combination of genes are correct?
