Hahaha I like the pixelation for the flies while matting. Much respect and best wishes.

Thanks, that was great. I am working with late embryo Drosophila cell lines, but it is useful to understand the whole organism and life-cycle. Many Thanks.

Brilliant lecture! It's a great pity that you've not had time to complete the series.

This is a very good lecture showing how we can understand complex development and genetic biology from a simple organism and rapidly growing kitchen insect fly. Thanks

please make more videos on development biology... your teaching is interesting, and make sure topics should be molecular level...... anyway thanks for these 5 videos.

It's perfect! Thank you , i really enjoy it .I just have a question, are you sure there are 11 body segments? , i have read that it's 14 of them ..

@JasonPellettieri 10 жыл бұрын

Thanks for your comments, Tannia. In answer to your question, the larvae have 8 abdominal and 3 thoracic segments, plus the head. The head is formed from 3 of 14 total embryonic segments (so what you read is correct) but these are not clearly distinguishable at the larval stage, so Drosophila biologists often refer to 11 larval body segments (8 abdominal and 3 thoracic) plus the head, as I did here. Hope that helps.

EERrrrmm that big picture of a fly you start with is not Drosophila melanogaster. In fact, I would even say it looks like its in the steganinae (maybe Leucophenga?)

@JasonPellettieri 7 жыл бұрын

A friend/professor who did doctoral research on fly development felt confident it’s Drosophila, and probably melanogaster (female). But you could be right (hard to evaluate your expertise with a user name like Arrrrggghhhh!). In any event, I primarily use open source images in these videos, so that I can make them freely available without having to obtain a million copyright permissions. My intent with this particular picture was simply to illustrate the major features of the Drosophila body plan.
