Which statement about homologous chromosomes is FALSE?
Select one:
a. They contain the same genes in the same places along the length of the chromosome
b. One member of the homologous pair came from your mother, the other from your father
c. For a particular gene, one member of the pair may have one allele, while the other has a different allele
d. They are joined together at the centromere as the two halves of the typical X-shaped chromosome

chromosome 21. That egg was fertilized by a normal sperm to create an embryo. This
would lead to an individual

B) who would be normal in chromosomal number
C) who had trisomy
D) who was triploid
