In a dihybrid cross, there are 16 possible ways for parental alleles to combine. The image below is a 4 by 4 box-a Punnett square for the pea plant dihybrid cross (FfHh X FfHh). It shows all the possible genotypes and phenotypes that the offspring can have (one in each of the 16 boxes).
100 percent of the global warming over the past 60 years is human-caused, according to the IPCC's latest report. The IPCC is 95 percent confident that humans are the main cause of the current global warming. Photograph: Jianan Yu/Reuters The fifth Intergovernmental Panel on Climate Change (IPCC) report states with 95 percent confidence that humans are the main cause of the current global warming. Many media outlets have reported that this is an increase from the 90 percent certainty in the fourth IPCC report, but actually the change is much more significant than that.
It will make the case that humans are causing global warming with carbon emissions even more strongly upgrading it from âvery likelyâ in 2007 to âextremely likelyâ it is manmade. But scientists are under pressure to explain why the warming has not exceeded 1998 levels although the decade 2000-2010 was the hottest on record.
