Mendelian Inheritance (Mendel's Third Law)
Product Code : SCL-BLE-11772
Mendelian Inheritance (Mendel's Third Law) (SKU SCL-BLE-11772) is a genetics teaching aid on the third of Mendel's laws, drawn from his work on the pea plant and the 7 main contrasting traits he compared. It helps students see how two different traits are inherited at the same time, in school biology, senior secondary genetics and college courses. Requests for it go to Science Lab Supplies in Ambala, India, which arranges the quotation, packing and dispatch.

Applications and Experiments for the Mendel's Third Law Teaching Aid
Teachers can use it to explain how Mendel crossed plants differing in two traits, such as seed shape and seed colour, and found that the traits were passed on independently. It fits the inheritance chapter of Class 12, college genetics and revision of dihybrid crosses for entrance examinations.
- NCERT Class 12 Biology, Principles of Inheritance and Variation: inheritance of two genes, the dihybrid cross and the 9:3:3:1 ratio.
- CBSE Class 10 Science, Heredity: an extension activity on how two characters are inherited together.
- Connecting independent assortment with DNA, by pairing bases on the DNA Activity Model and showing replication on the DNA Model on Base.
- B.Sc. genetics: chi-square testing of dihybrid ratios and the exceptions caused by linkage.
Standard Scope of Supply
Each order line brings one Mendelian Inheritance (Mendel's Third Law) teaching aid, and its format and dimensions are stated on the quotation. The first- and second-law items, DNA models and meiosis slides are not included, but any of them can be quoted in the same document.
Packing, MOQ and Lead Time
You can ask for one piece or for a quantity covering every school in a group. Each quotation spells out packing, delivery time and price for that number, and the full Mendel sequence or other biology charts and models for schools can be priced at the same time.
With an Importer-Exporter Code, Science Lab Supplies is in a position to ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). A short note through the contact page starts a quotation; larger lists suit the enquiry cart, and the lab tender page covers public tenders.
Frequently Asked Questions
What is Mendel's third law?
Where three laws are counted, as in the NCERT sequence of dominance, segregation and independent assortment, the third is the law of independent assortment: factors for different traits separate into gametes independently of each other.
Is this a wall chart, and what size is it?
The format and size are confirmed on the quotation. The first-law item in the same group is a laminated 70 x 100 cm wall chart; ask the team whether this teaching aid matches it before you order.
Why is the 9:3:3:1 ratio linked to this law?
When two independently assorting traits are crossed, the second generation shows four combinations in roughly a 9:3:3:1 ratio. Mendel's results with pea plants matched this pattern, which supported independent assortment.
Who provides the Mendel's Third Law teaching aid?
It is a supplied item provided by Science Lab Supplies of Ambala, India. The company sends quotations to schools, colleges and dealers and takes care of packing and dispatch once an order is placed.
