<h3><u>Answer;</u></h3>
Whereas segregational petites exhibited Mendelian inheritance, both neutral and suppressive petites followed non-Mendelian patterns that were consistent with the involvement of an extranuclear agent
<h3><u>Explanation</u>;</h3>
- Mutations that yield defective mitochondria are expected to make cells grow much more slowly. These mutants were called petites to describe their small colonies compared to large wild type colonies.
- Petite mutants could not grow when cells had an energy source requiring only metabolic activity of mitochondria - needed sugar as well which is part of glycolytic pathway.
- Segregational petites, segregated in mendelian manner during meiosis. mutations cause defects in genes in cell nucleus encode proteins necessary for mitochondrial function.
- Vegetative petite mutants do not segregate in mendelian manner; two types: neutral and suppressive; carry mutations in mitochondrial genome itself; when two yeast cells are mated, daughter cells inherit mitochondria from both parents.
- Neutral petites lack most of their mitochondrial DNA; when mated with wildtype, the wildtype give their mitochondria so all cells display a normal phenotype.
<span>I think you meant chromosome aberration. In that case, it is when a chromosome is “abnormal,” such as having a “wrong” structure or missing a chromosome. There are four types of mutations: deletion, duplication, inversion, and translocation. The fifth is deficiency, when a chromosome is lost during the development stage of a fetus. I’m not an expert on this, but I hope it helped</span>
B. Sexual reproduction increases genetic diversity
Answer:
The chloroplasts in autotrophic organisms (most often plants and algae) capture energy from the sun.
Explanation:
The chloroplasts take in this energy from the sun, and converts it into energy called ATP through the process called photosynthesis.

Did a bit of research, found a cool one.
Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or foot when hearing, seeing, or kicking something? Which side do people use the most? In this science project, you will get to find out!
