What else can I help you with?
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.
What is x linked trait?
Normally sex-linked traits are carried only on the X chromosome, meaning a sex-linked gene can only be inherited from the father's X or the two mother's X's. However, there are occasions where the trait is carried down by the Y chromosome, meaning only the males would inherit it, and it would be expressed. This is very uncommon because the Y chromosome carries very little genetic material/information in comparison to the Y chromosome.
What is the designation for the short arm of a chromosome?
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
Is the smallest gene cell chromosome?
Chromosome 21 is the smallest human chromosome. Inside of the chromosome, there are 48 billion nucleotides, the building blocks of DNA.
What various types of genetic material in order from simplest to most complex?
nucleus → chromosome → gene

Is an x chromosome and chromosome the same thing?
An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
Which chromosome contains the sex gene?
chromosome 1 chromosome 1
What are the name of 23 chromosomes in human body?
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
What is the designation for the short arm of a chromosome?
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
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.
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
The number and structure of what can help to determine evolutionary relationships between species?
The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.
What is the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
What condition is carried on a chromosome other then the sex chromosome?
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
