Answer:
Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.
Explanation:
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.

Cell shrinkage will be the answer
Answer:
Fomite transmission.
Explanation:
This is a form of indirect transmission. This type of transmission occurs when inanimate object are involved in the indirect transfer of the pathogens to an uninfected host.
The inanimate object is often referred to as fomites.
In this example, the facilities in the daycare would be the fomites involved in the indirect transfer of the pathogen from one child to the other child.
