A scientist named Thomas Hunt Morgan studied genetics in fruit flies. Specifically he looked at wild type (normal) wings versus vestigial (shortened) wings. When he crossed a wild type female with a vestigial male he expected to see 50% parental phenotypes and 50% recombinant phenotypes in the offspring. However, what he actually found was 83% parental phenotypes and 17% recombinant phenotypes. What does this suggest about the genes he was studying? How do the percentages help us determine this?

In 2015, about ten percent of total u.s. energy consumption was from renewable energy sources. renewable energy plays an important role in reducing greenhouse gas emissions. when renewable energy sources are used, the demand for fossil fuels is reduced. sanjay and his family want to cut back on their use of non-renewable resources at home. they are thinking of an alternate way to heat their home without adding more greenhouse gases or pollutants to the environment. which renewable resource would not fit into their plan? a) solar power b) burning wood c) constructing a wind turbine eliminate d) generating hydroelectric power
