Using a pre-drawn template can be helpful during a consultation to explain single gene inheritance. Our template shows one pair of chromosomes for each parent.

Biologists have long puzzled about how evolutionary selection, known for its ruthless requirement for efficiency, allows the existence of males - when in so many species their only contribution to reproduction are spermatozoa. But research published today in Nature shows that sexual selection - when males compete and females choose over reproduction - improves population health and protects against extinction, even in the face of genetic stress from high levels of inbreeding.

Ebola is an infectious disease, which has become a pandemic crisis causing around 5000 deaths in 2014, with a 50% mortality rate among those who have contracted the virus. The outbreak in West Africa was first reported in March 2014, and every natural case of Ebola has been in Sub-Saharan Africa with Liberia, Sierra Leone and Guinea at the epicentre of the crisis. This key stage 3-5 resource, produced by GA Consultant and Secondary Phase Committee Co-Chair Stephen Schwab, includes classroom activities and teaching ideas, and explores geographical facts, concepts and the impact the virus has had on the communities affected.
