The inversion would suppress recombination.
In Drosophila, the mutations which are recessive are lethal or recessive sterile. Balancer chromosomes are used to hold the deleterious mutations in stable shares as well as to save you recombination with the aid of suppressing.
Chromosomal inversions prevent the recuperation of recombinant chromosomes in ways.
- the crossovers do now not shape within the location of inversion breakpoints, due to the fact synapsis is inhibited.
- unmarried crossovers' inner inversions result in aneuploid gametes that cannot give upward push to normal progeny.
Drosophila is a genus of flies, belonging to the own family Drosophilidae, whose participants are often referred to as "small fruit flies" or (much less regularly) pomace flies, vinegar flies, or wine flies, a connection with the feature of many species to linger around overripe or rotting fruit.

<h3><u> Answer;</u></h3>
B. organelles
<h3><u>Explanation;</u></h3>
- Eggs contribute 50% of the chromosomes as well as cytoplasm and cellular mechanisms required for the cell to thrive and replicate.
- Mitochondria for example are particularly important to the embryo but are only passed from mother to child via the egg.
- Sperms on the other hand, are just packets of DNA.
