En los seres humanos, hay cuatro (4) grupos sanguíneos: A, B, AB y O que son el resultado de la combinación de tres alelos diferentes de un solo gen. Se sabe que los glóbulos rojos pueden tener tipo de sangre A, tipo de sangre B o tener tipo de
sangre O. El tipo de sangre A está determinado por el alelo IA y el tipo de sangre B, por la del IB. Entre ambos hay
codominancia. El alelo IO determina el tipo de sangre O y es recesivo frente a los otros dos.
Con base en la lectura anterior revise el siguiente problema y la respuesta, está correcta si o no, explique ¿por qué?
Problema: Un hombre de grupo sanguíneo A y una mujer de grupo sanguíneo B tiene cuatro hijos, de los cuales uno
pertenece al grupo AB, otro al O, otro al B, y otro al A. ¿cuál puede ser el genotipo de los padres?
Respuesta: El padre tiene que ser AO y madre tiene ser BO porque si no tuviesen el O no podría haber salido un hijo con
grupo sanguíneo O ya que el O es recesivo.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
