Answer:
List of options to choose from to complete the question:
A. Aneuploidy
B. Polyploidy
C. Translocation
D. Monosomy
E. Duplication
The CORRECT ANSWER IS A.
A. Aneuploidy.
Explanation:
Aneuploidy results from unusual number of chromosomes in a cell, e.g a human cell with 45 or 47 chromosomes other than 46.
It's mostly seen in Trisomy e.g. trisomy 21 (Down syndrome), trisomy 13 (Patau syndrome) and trisomy 18 (Edwards syndrome).
All living things are made up of more than one cell
Cells Can Replicate Their DNA Precisely. Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNAreplication is one of the most basicprocesses that occurs within a cell.
(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.
(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.
(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
