genes
A chromosome that has been broken and rejoined in a reversal sequence has undergone?
inversion
What are the differences between translocation and inversion mutations?
Translocation is when nonhomologous chromosomes exchange segments, like when chromosome 1 exchanges parts with chromosome 5. Inversion is when broken segments of the chromosome is inserted backwards.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.

What does deletion chromosome consists of?

What is an antonym for chromosome?
Chromosome does not have an antonym.
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
