Reinforce concepts related to meiosis and sexual reproduction. Students compare terms such as diploid and haploid, and label an image.
Helpful review on chromosomes which focuses on terms such as diploid and haploid, mitosis and meiosis, and zygote versus gamete. Students also practice chromosome math using chickens as a model, which have 78 chromosomes in body cells. Worksheet is intended as a review for basic level biology students.
Students cut out each chromosome and organize them in pairs based on their patterns and size, they number them to determine the diploid number for the species and then consider a situation where the animal has an extra chromosome. Students must determine which set has the extra chromosome and consider the concept of trisomy.
