i.e. the Y, W, U and V chromosomes, often, but not always, undergoes sex-specific evolution, including degeneration and gene loss as a result of cessation of recombination, the causes of which are discussed below [7,11]. The Y, W, U and V chromosomes are therefore also known as non...
Common to all these sex chromosome systems is that the sex-limited sex chromosome, i.e. the Y, W, U and V chromosomes, often, but not always, undergoes sex-specific evolution, including degeneration and gene loss as a result of cessation of recombination, the causes of which are discussed...
Why are chromosomes not always visible? Why does meiosis start with a diploid cell? Why is it necessary for the daughter cells of meiosis to result in 23 chromosomes, rather than 46? How are chromosomes arranged in a karyotype? Why are somatic cells diploid?

Autosomal Chromosomes: Chromosomes are divided into two types: autosomal and sex chromosomes. Sex chromosomes are those that determine whether the human is male or female. If the person receives two X chromosomes, it will be female, and if it gets one X and one Y it will be male. ...

It has always been expected that dosage compensation (DC) of X/Z gene expression between the sexes (Lyon, 1961), and with the autosomes, was critical for life (Nguyen and Disteche, 2006). Indeed, the imbalance in one sex of X and autosomal genes is fatal to human embryos and ...
Does DNA replication occur in meiosis? Do all somatic cells have 46 chromosomes? How many pairs of chromosomes are in the nucleus of a human cell? Is this number always the same? What do chromosomes contain? Does each egg cell in a human woman have identical DNA?
Sperm cells carrying the Y chromosome will a) always result in the conception of a female baby. b) will result in the conception of twins more often than those carrying an X chromosome. c) typically result in children with brown eyes. d) usually carry les ...
