New Mexico and Wyoming may contain rivers that eventually join the C<span>olorado River. Even though the main stem of the Colorado River does not pass through these states, The rivers in these states may act as tributary rivers to the Colorado River. To understand this, you need to understand how water moves across the surface of the Earth from a higher elevation to a lower elevation, and the concept of a river catchment. </span>
Answer:
All of their sons would be colour blind
Explanation:
Given that colour blindness is X linked recessive condition which means that the gene is located on X chromosome and when present in recessive homozygous condition, it will be expressed. Hence if XC is dominant allele and Xc is recessive allele, XcY and XcXc will be colourblind.
The male has normal vision and males have only one X chromosome so his genotype is XCY.
The female is colourblind and females have two X chromosomes so her genotype is XcXc.
Their children:
XC Y
Xc XCXc XcY
Xc XCXc XcY
All the sons have XcY genotype where gene for colourblindness is in recessive condition hence all of their sons would be colourblind.
There are many lines of evidence which clearly show that the atmospheric CO2<span>increase is caused by humans. The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half). There is no question whatsoever that the CO2 increase is human-caused. This is settled science.</span>
