Thanks. I recorded this in a home studio. The screen is a piece of tempered glass with the 3M rear-projection film applied to the side opposite I'm writing on. Lighting is 10 strategically placed lamps with CFL bulbs. Projector (1024x768) and camera are pretty basic. After recording, I adjust exposure levels to boost contrast and edit in Final Cut Pro X. If there's enough interest, I may record a "how-to" video at some point, but for now, I need to finish some more lectures!

Looking forward for more videos on topics such as cell totipotency, determination, commitment etc. In addition to that different specimen developmental biology.

I am teaching developmental biology and your lecture is incredible! Very clear, to the point, precise and engaging. Do you have more lectures? I enjoy it very much! Thank you for doing this!

Thanks! Between live teaching and research, I don't have as much time for this project as I'd like. But I am working on more lectures and will post them to my KZfaq channel when they're done.

I really like the look of this presentation. I'm wondering if you wouldn't mind answering a couple of questions about the technology you're using: I'm assuming it's 3m rear projection film on glass for the display--but is the film on the side that you're writing on, or is the film on the reverse of the glass? And, how bright are the lights that you're under? I know brightness is relative, but is it a studio, or just regular room lighting? And do you know the type of projector being used? Thanks!

what happens if we separate the cells in an embryo? Will they re-attach to each other and become normal?

@ShawnDypxz 7 жыл бұрын

It depends on waht type of cleavage do the organism have. Two types of cleavage .Determinate and Indeterminate.. If the early blastomeres are separated then, those each blastomere develop into individual embryo. Thats indeterminate cleavage as seen on human ... Other type is determinate in which early blastomeres must be intact to form a embryo. Google for the examples

Hello Jason, Can you please tell me the Title of Unit 1, Lecture 2....... because I couldn't find this lecture.....I can only search Unit 1, Lecture 1(Little Man), 3 (How the Maggot Gets Its Stripes) and 4 (Overview of the model organism C. elegans). Do you also have other Units???? Thanks

@JasonPellettieri 9 жыл бұрын

Sorry, I haven't recorded Lecture 2 yet. I hope to have that (and other lectures in Unit 1) posted sometime soon. Additional units will not be completed for a while.

Why do we need 1 (Gametogenesis) and 2 (Fertilization)? In other words, why is sexual reproduction necessary? Couldn't we just start at 3 (cell division), and whenever we want to reproduce, we just send off a single cell on its own, to start its own reproducing cycle (from 3)?

@patldennis 3 жыл бұрын

A population of clones has very low genetic diversity. One benefit of sexual reproduction is being diploid, and the potential for heterozygosity. A second benefit is the recombination of our parents chromosomes during meiosis when we form gametes-it mixes up the available alleles in each individual, but maybe not so beneficial for us humans since we generally have 1 offspring at a time anyway.
