By grouping images of a fetus' homologous pairs together and arranging them by shape and size, scientists can easily see whether
the baby has

Answer 1

Down syndrome, which results from having the wrong number of chromosomes

Step-by-step explanation:

Down's syndrome is a specific type of genetic defect in which a person has three copies of the twenty-first chromosome. Scientists can now determine whether a fetus has the extra chromosome—and thus Down's Syndrome—by creating a karyotype like the one pictured here.

Screening for genetic diseases that involve mutations in the construction of the genes instead of the number of genes may not be as straightforward.

Answer 2

Step-by-step explanation:

Genetic conditions such as trisomy (three chromosomes) or monosomy (only one chromosome). They can also determine the fetus' gender by looking at the XY / XX chromosomes.
