"Meet the Y chromosome – the 'Master Key' to unlocking male genetic traits and lineage! 🔑🧬 It's responsible for maleness and fertility in males. Here is an amazing article explaining the world of the Y chromosome: https://buff.ly/3sO4mkS #YChromosome #Genetics #ScienceMystery"

Phenotype, autosomes vs sex chromosomes In genetics, the phenotype is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. An autosome is chromosome that is not a sex chromosome . The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosome pairs which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA. Youtube video: https://lnkd.in/dkmbsuxG #nikolaysgeneticslessons

Probability in Genetics In genetics, theoretical probability can be used to calculate the likelihood that offspring will be a certain sex, or that offspring will inherit a certain trait or disease if all outcomes are equally possible. It can also be used to calculate probabilities of traits in larger populations. Youtube video: https://lnkd.in/dBunr9jw \#nikolays_genetics_lessons

Genetics; XY system vs XO and haplodiploidy explaned The X0 sex-determination system is a system that determines the sex of offspring among grasshoppers, crickets, cockroaches, and some other insects. In this system, there is only one sex chromosome, referred to as X. Males only have one X chromosome \(X0\), while females have two \(XX\). The zero \(sometimes, the letter O\) signifies the lack of a second X. Maternal gametes always contain an X chromosome, so the sex of the animals' offspring depends on whether a sex chromosome happens to be present in the male gamete. Its sperm normally contain either one X chromosome or no sex chromosomes at all. In a variant of this system, certain animals are hermaphroditic with two sex chromosomes \(XX\) and male with only one \(X0\). The model organism Caenorhabditis elegans a nematode frequently used in biological research is one such organism. Some Drosophila species have X0 males. These are thought to arise via the loss of the Y chromosome. Youtube video: https://lnkd.in/dhZ2bNsW \#nikolays_genetics_lessons

Silene latifolia: The Classical Model to Study Heteromorphic Sex Chromosomes #Work done in Genetics Research lab hundred years of research efforts and its most conspicuous property is huge and well differentiated heteromorphic sex chromosomes, XX in females and XY in males. Due to this property the S. latifolia sex chromosomes have been often used for cytogenetic studies as well as for flow sorting and laser microdissection. Nowadays S. latifolia is the focus of genomic studies, molecular mapping, phylogenetic and population genetics analyses.

Is there a link between pollution and genetic mutations regarding the development of Autism Spectrum Condition (ASC)? According to eye-opening research by Heather Volk (PhD) from Johns Hopkins University, pregnant women with specific genetics could give birth to autistic children after being exposed to SMOG or traffic pollution. Can the findings of this groundbreaking study help prevent the development of ASC? Please share your thoughts in the comment section below.

The genus Microtus have high karyotypic diversity. The existence of notable differences in the length of its sex chromosomes contributes to this variation. Variations in size are attributed to the enlargement of their heterochromatin content, which is of such magnitude in some species that they are referred to as "giant sex chromosomes". Here, we perform an intra- and interspecific analysis of the molecular composition of the heterochromatic blocks in three species with giant sex chromosomes (Microtus chrotorrhinus, M. cabrerae and M. agrestis). Our results show that the heterochromatic content is very similar in both the X and Y chromosomes of M. chrotorrhinus, and that their molecular composition is more closely related to the heterochromatic blocks of M. agrestis than to the sex heterochromatin of M. cabrerae; however, species-specific differences do clearly exist. Interestingly, the euchromatic regions of the X chromosome of all three of these species share a homologous region composed of heterochromatic-related sequences. Our results therefore reinforce the idea that certain similarities in the original organization of these X chromosomes could have facilitated in their later enlargement. #Research Work in Genetics #Cytogenetics-Saptarshi Mukherjee and mÿ team #Industrial Genetics #Today's Sample #We Are publishing this work very soon
