3.- Resuelve los siguientes ejercicios. Utiliza los cuadros de Punnett. a.- En los guisantes las flores de color rojo son dominantes sobre las de color blanco. Cruce una planta de flores roja homocigótica con una de flores blancas.
Indique en porcentajes el fenotipo y el genotipo de F1.
b.- Averigua el fenotipo y el genotipo de F1 si se cruza un conejo de pelo negro homocigótico
dominante con una hembra de pelo blanco homocigótico recesivo.
c.- En los perros pastor alemán las orejas rectas son dominantes sobre las caídas.
Cual será el fenotipo y genotipo de los cachorros de F1?

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

wegner's theory did not explain how the continents could move

explanation:

multiply it by 5 in order for you to understand i cant give an exact answer.
