A wheat plant that is light green in color is found growing in a field. Biochemical analysis reveals that chloroplasts in this plant produce only 50% of the chlorophyll normally found in wheat chloroplasts. Propose a set of crosses to determine whether the light-green phenotype is caused by a mutation in a nuclear gene or in a chloroplast gene.

Set of crosses:

Wild-type male x light-green female  

Light-green male x wild-type female

Explanation:

Chloroplast genes are inherited maternally and, therefore it would be expected to observe this mode of inheritance:

- Wild-type male x light-green female >> offspring 100% light green  

- Light-green male x wild-type female >> offspring 100 % wild-type

Moreover, nuclear genes are inherited from both parents, and, therefore, in the case of complete dominance, it would be expected to observe the following results:

1- When wild type is dominant:

- Wild-type male x light-green female >> offspring 100% wild type

- Light-green male x wild-type female >> offspring 100% wild-type

2- When light-green is dominant:

- Wild-type male x light-green female >> offspring 100% light-green

- Light-green male x wild-type female >> offspring 100% light green

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
