Why do chromosomes resemble the letter X ?
Homework Answers
Please find the answer below:
During the S phase of the cell cycle, there is duplication of chromosomes which becomes double-stranded. Each of these strands is called chromatid. The two chromatids are joined together at the centromere by proteins. During the prophase stage of mitosis, the replicated chromosomes begin to condense and they appear as thick 'X' shaped structure. Thus the chromosomes resemble the letter X.

Q 14. Why do offspring resemble their parents, but only approximately? Some factors that might be relevant would include quantitative-trait loci, the phenotypic variance, the additive genetic variance, and the environmental variance. Just dropping these names (and others) does not really explain anything, unless you say what they are and how they interact to affect the resemblance between parents and offspring. 11.01 • 1978 • 1976 Offspring beak depth (mm) 8.0 9.0 10.0 11.0 Midparent beak depth (mm)

Description Human chromosomes are classified as either autosomes or sex chromosomes, and the inheritance patterns of traits vary depending on the type of chromosome they are located on. Why is this the case? Instructions Read Chapter 5 in Essentials of Genetics, then respond to the prompt below: Prompt: In humans (and most animals), sex is determined using the X-Y system. The basis of this system is that the number of X chromosomes and Y chromosomes determines whether the individual will...
