A single cell RNA seq analysis identifies 25 population of epidermal cells .
<h3>What is single cell transcriptomics used for?</h3>
Single cell transcriptomics are being used to create reference maps of healthy human tissues, organs and systems at single cell resolution.
An essential model system for studying stem cells and tissue regeneration is the mouse epidermis with its hair follicles. To demonstrate how the cellular heterogeneity of the murine telogen epidermis is controlled at the transcriptional level, we used single-cell RNA-sequencing in this study. 25 different populations of interfollicular and follicular epidermal cells were identified by impartial clustering of 1,422 single-cell transcriptomes. With previously unheard-of resolution, our data allowed for the reconstruction of gene expression patterns during epidermal development and along the proximal-distal axis of the hair follicle.

Answer:
Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.
Explanation:
The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.
Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.
The other options are not correct because:
- <em>Drones, with half of the chromosomal charge, </em><u><em>cannot be diploid</em></u><em>.
</em>
- <u><em>Monosomy and trisomy</em></u><em> are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.</em>

A child's eye and hair color are determined by its parents that pass on the genes for red, blonde, brown, black, curly, straight hair, etc, etc.
