Between 1955 and 2012 the global tfr rose from 2.4 to 5 true or false

I believe it is actually false.  It dropped from 5 to 2.4.  Hope it helps!

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )
