How do the crystals in a metamorphic rock align if the rock has been exposed to extreme pressure? perpendicular to the direction of force equally in all directions parallel to the direction of force what is the protolith for the metamorphic rock marble? limestone sandstone basalt what is the protolith for the metamorphic rock quartzite? limestone andesite sandstone regional metamorphism tends to make rocks more foliated. true false

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
