14. Genetics 3 – Linkage, Crossing Over

MIT 7.016 Introductory Biology, Fall 2018
Instructor: Adam Martin

In his third lecture on genetics, Professor Martin picks up from the last lecture on eye color in fruit flies, and then continues with Mendelian inheritance. He then talks about linkage, crossing over, and gene mapping.

Ah yes. I have found yet another god. It's always just 1000x better when a professor teaches on a blackboard. Keep up the good work. Great stuff.

It's very helpful for like me students who have no accessibility to standard content like this..

Every time the professor bows down to writte, his respect increases in my heart.

(On Thursday of February 2, 2023). Biology and the Genetics Therein: 1) Linkage (Gametogenesis has the Cellular Division known to Make a Diploid Cell-Haploid Cells) Where the Recombination Possibility of Linkage can Occur; 2) Crossing Over or the Meiotic Event might have a Crossing Over ; 3) Gene Mapping Is an Effort to Characterize the Genotype (Genome) along the lines of Quantity, Length From the Centromere, (But essentially would be to map and correlate site, structure (Genotype Quantification) with Function; Amyotrophic Lateral Sclerosis (ALS) a typically Autosomal Dominant (AD) Inheritance Pattern However unlikely there can be an X-Linked Pattern Making the likely hood more in favor of One Particular Sex Phenotype over the Other Sex based on the Affected Parent. The Meiosis Phase 2 Result is missing in the Illustration but hopefully not crucial in the Essence of this Lecture. PhD Adam Martin es geht sehr Gut aber Gesund(tight) an ihnen Auch (Witzig). Heil!

The user making extremely negative comments here is doing it on many of this professor's videos, which seems extremely suspicious to me. User with username: kdrl nakle (at the time of me making this comment) has commented negatively in similar respects for videos: 13, 14, 15 and 16 and probably more but I suspect you understand my reasoning here.

I've got lost from centromere linkage and tetrad analysis :(
What is the meaning of centromere linkage? Does it mean that centromere linked genes are not recombined?
