Two unicorns mate. one unicorn has a white horn and has genotype hhww (has horns and the horn is white). the other unicorn has the genotype hhww (it has genes for black horn, but no horn). what is the likelihood that they will have a colt with a white horn ?

ok so for one you got 2 genes of color and two genes of horn/no horn

so that makes 1/4 chance of a white horn but then with the gene of the no horn it lowers down the chance to about 1/6 or 1/8 i think but yes other genes can counter act and lower or higher the chances of white horn

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
