If an egg that is missing a chromosome is fertilized by a normal sperm, the result is Blank______.Multiple choice question.euploidymonosomytrisomytriploidy

Break Down the Problem

1. Identify the condition of the egg (missing a chromosome).
2. Identify the contribution of the sperm (normal).
3. Determine the genetic outcome of fertilization.

Relevant Concepts

1. A normal egg contains 23 chromosomes. An egg missing a chromosome would have 22 chromosomes.
2. A normal sperm contributes 23 chromosomes, leading to a potential total of 45 chromosomes after fertilization.

Analysis and Detail

1. The fertilization of an egg with 22 chromosomes by a sperm with 23 chromosomes results in a total of $22 + 23 = 45$ chromosomes.
2. The resulting condition can be classified as monosomy, which occurs when there is a missing chromosome in a pair (in this case, one pair has only one chromosome instead of the usual two).

Verify and Summarize

1. Since the egg is missing one chromosome, we verify that this leads to an overall deficit in the normal chromosome count.
2. This condition, where there is one less than the diploid number (46 in humans), signifies monosomy.

Final Answer

The result is monosomy.
