Short sex chromosome discovered in fruit flies?
The short sex chromosome in fruit flies, known as the Y chromosome, carries genes related to male traits and fertility. It determines the sex of the offspring when paired with an X chromosome. In evolutionary terms, the Y chromosome has undergone significant degeneration, leading to a size reduction and loss of genetic material compared to the X chromosome.
Can you live with a y-chromosome and no x-chromosome?
No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.
Why x chromosome is placed in group c and y chromosome placed at the end of forth row?
The X chromosome is generally larger and carries more genetic information compared to the Y chromosome. In the traditional system of organizing chromosomes by size, the X chromosome is placed in group C as it is larger, while the Y chromosome is smaller and simpler, so it is usually placed at the end of the fourth row.
What is the nuclear envelope compared to in a factory?
The nuclear envelope can be compared to the walls and gates of a factory. It surrounds and protects the contents of the nucleus, acting as a barrier that controls what molecules can enter and exit the nucleus, similar to how walls and gates control access to a factory.
What part of the factory is compared to lysosomes and why?
The waste disposal system of a factory can be compared to lysosomes in a cell. Lysosomes contain enzymes that break down waste materials and cellular debris, similar to how the waste disposal system of a factory removes and breaks down waste products to keep the factory running efficiently.
A green leaf can be compared to a?
factory
How does the order of genes in one member of chromosome pair compared to the order of genes on the other chromosome?
Most homologous pairs look alike. They carry genes for the same characteristics and line up on the chromosome in the same order!

The structures found in a living cell can be compared to the parts of a factory that produces cars. Which part of the factory is most similar to the nucleus of a living cell?
Factory Manager -> Control Center.
The chromosome number after meiosis is denoted as?
The chromosome number after meiosis is denoted as haploid, meaning that the cells have half the number of chromosomes compared to the original cell. In humans, the chromosome number after meiosis is 23.
Why living organism always compared to chemical factory or machine?
because we are smart we have free will
Why are individuals with an extra chromosome 21 which causes Down syndrome more numerous than individuals with an extra chromosome 3 or chromosome 16?
Individuals with Down syndrome are more numerous then individuals with an extra chromosome 3 or 16 because the those conditions are much more likely to be fatal (resulting in miscarriage or other early deaths).
