Sex determination in birds The sex chromosomes in birds are designated Z and W, and the male is the homomorphic sex (ZZ) and the female heteromorphic (ZW). In most avian species the Z chromosome is a large chromosome, usually the fourth or fifth largest, and it contains almost all the known sex-linked genes.

Did you know about Turner’s syndrome (TS)? Every 1 in 2,500 women is born with it. TS is a genetic disorder that occurs due to abnormalities with the sex chromosomes. #LifeClues #LifeCluesfertility #geneticdisorder #Turnerssyndrome #Turnersyndrome #TS #sexchromosomes #LifeCluesfertility #geneticdisorder #Turnerssyndrome #Turnersyndrome #TS #sexchromosomes

Sex chromosomes and sex determining mechanisms in birds Do male or female birds determine gender? In a ZW female embryo, the single copy of DMRT1 permits the gonad to develop into an ovary, which makes estrogen and other related hormones; a female bird results. This kind of sex determination is known as gene dosage . It's the difference in the number of sex genes that determines sex.

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/d-eSEMVf \#nikolays_genetics_lessons

There are other sex reversal methods used in tilapia. One method is known as genetic sex reversal, where specific genetic techniques are used to manipulate the sex of the fish. This involves manipulating the fish's chromosomes or genes to promote the development of the desired sex. #SRT #TILAPIA #Climatechange #sustainability

What would be the sex of XXY individual? Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby.

It’s Mothers Day. What do you know about Parthenogenesis? Its the development of a new organism from an unfertilized sex cell. It's not common. -It almost only happens with female sex cells. -Rarely does a male sex cell develop into a new individual - It isn't common and happens in only around 2,000 species. Its most common with Ants, Bees, Wasps and Aphids. Sociable organisms Not every creature needs a father. But virtually all creatures need a Mother. Happy Mothers Day. Isn't Nature amazing? #Parthenogenesis #MothersDay #No4thFloor

💡 #DidYouKnow: Humans have 23 pairs of chromosomes: 22 pairs of autosomal chromosomes and one pair of sex chromosomes (X or Y). Unlike #hemophilia, which is due to mutations on the X chromosome, other rare clotting factor deficiencies are due to mutations on the autosomes.

Environmental, sex-specific and genetic determinants of infant social behaviour in a wild primate. Shows sex differences in grooming at a young age and that age at first grooming is heritable and so, can be shaped by natural selection. https://lnkd.in/g-iE7MfV
