n Holstein cattle the allele for black hair color (B) is dominant over the allele for red hair color (b), and the allele for polled (P), or lacking horns, is dominant over the allele for having horns (p). What is the expected phenotypic ratio of the offspring of a BbPp × BbPp cross if these alleles sort independently? 16 black/polled : 0 black/horned : 0 red/polled : 0 red/horned 12 black/polled : 0 black/horned : 0 red/polled : 4 red/horned 4 black/polled : 4 black/horned : 4 red/polled : 4 red/horned 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned

hi,

the answer is third world countries, take for instance china, they restricted each family with only one child,

hope this !

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
