A science teacher uses different colored candies to represent alleles in a genetic experiment in class. One student begins to eat the candy. What is the greatest concern?
The siblings received different genes from the parents.
traits are determined by genes found within chromosomes
Ingesting an unknown chemical
the double helix structure is demonstrated
One allele may be dominant over the other.
genes
They contain the organism's genetic information.

What will happen if an organism inherits different alleles for a trait?
The siblings received different genes from the parents.

genes
They contain the organism's genetic information.
nucleus
Students study how genetic traits are passed down from parent to offspring. The students learn that DNA is unique to each individual organism. Students use chenille sticks and plastic beads to create a model of DNA. An advantage of this model is..

Gregor Mendel, while studying pea plants, noticed that certain traits in the pea plants were passed from parent to offspring. He concluded that each plant had a set of instruction for each trait that was passed on by each parent. Today we know...
