During the process of creating a sperm cell, one chromosome does not separate, the resulting sperm cell has an extra chromosome. This is called If this sperm fertilizes an egg, how many chromosomes with the baby chick have?

The correct answer is trisomy and the baby chick would have 47 chromosomes instead of 46.

Explanation:

During the process of creating a sperm cell, one chromosome does not separate, the resulting sperm cell has an extra chromosome. This is called trisomy. Trisomy is a type of polysomy where the organism possesses at least one extra chromosomes than the usual. It is usually caused due to the failure of pair of homologous chromosomes to separate. This results in many diseases such as down syndrome.

If this sperm fertilizes an egg, there would be one odd extra chromosome, i.e. there would be 47 chromosomes than the usual 46.

Explanation:

1. Abnormal chromosomes most often result by an error during cell division. Chromosome abnormalities often happen by:

i) Errors during meiosis.

ii) Errors during mitosis.

2. If meiosis happens abnormally, then sperm cell may have an extra or less chromosome. It results in that a baby may have an extra chromosome called trisomy or have a missing chromosome called monosomy. This trisomy or monosomy can cause pregnancy loss, or health problems in a child.

3. A gain or loss of an extra chromosomes is called aneuploidy. A common form of aneuploidy is trisomy, is the presence of an extra chromosome in cells. People with trisomy  have three copies of a chromosome in each cell, a total of 47 chromosomes per cell.
