An experiment was performed to determine the mode of inheritance of two mouse genes, one for fur color and one for fur length. it is known that black fur (b) is dominant over white fur (b) and that long fur (l) is dominant over short fur (1). to determine how the genes are inherited, a cross was performed between two true-breeding mice, one with long black fur and one with short white fur. their progeny, the fi generation, all had long black fur. five fı male-female pairs were then crossed with one another. the f2 generation phenotypes for each cross are shown in

Which of the following best describes the expensive tissue hypothesis? brains require more energy, so the gut had to be reduced, and larger brains and tool use led to higher quality diets. increasing body size means that homo neanderthalensis had to include more fat in its diet. brains require more energy, so the gut had to be reduced as brains got bigger. brains require more fat, so the gastrointestinal viscera (gut) had to expand, and hands were needed to acquire more food.
