Table 183

________ shows an association with particular cancers, but research shows that a toxic agent in the environment may cause a disease, even though these agents actually promote the changes that result in cancer.

A(n) ________ containing both types of proplastids grows through the use of the cellular divi ellar gene, which is found in the chloroplasts or mitochondria.

maternal parent

The ________ decides what the offspring will look like.

sperm cell

The ________ does not produce proplastids.

Epigenetic changes

________ can be caused by certain agents in the cell nucleus and the genes that do not segregate in tobacco smoke.

Carl Correns

________ carried out one of the first experiments showing an extranuclear inheritance in 1909.

green pheno type

The ________ is found in four- o'clock plants and is due to the presence of functional genes in the chloroplasts.

Extranuclear inheritance

Chloroplasts

What are derived from proplastids? Answer with a single words or term.

egg cell

A(n) ________ contains offspring from a previous inheritance.

white phenotype
