You're welcome 😊

[@squiggan]

Thank you for the informative, easy to comprehend instructional video on zenes and the allele within a cell which is a part of our DNA, much appreciated. Wouldn't know this without the view, thanks again.

Very helpful! Thank you! This took the place of one-and-a-half hour long lectures at my intro bio class :)
My Professor does a great job also, but videos like this are useful for those of us that had to miss class for whatever reason. Keep it up, please!

Please sir...can u give best defination for Alleles.

[@BiologyLectures]

Dear Abhinav, Please find the defition below: An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous

[@parkhhind2621]

Does the Locus of each gene vary from male to female ?

[@BiologyLectures]

Locus of a gene may vary between males and females. Males and females have partially different genomes. Viewed from a purely reductionist standpoint, many differences between the male and female sexes are predicted to be rooted in differences between the genetic contents of male and female cells and differences in the expression of those genetic contents

[@ibrarshahswaty745]

Extremely comprehensive 🥰😊

[@BiologyLectures]

Thank you 😊

[@petclement-2020]

Since you explained that a chromosome is a condensed form of DNA so it can fit into the nucleus of the living cell...Hence it should be
DNAs
Chromosomes
Gene
Alele
