Parental genotypes: RrYy x RrYy
Offspring genotypes: RRYY, RRYy, RRyy, RrYY, RRyy, rrYY, rrYy, rryy
The conclusion is incorrect because there is a chance that the offspring may have the genotype rryy, in which it has no dominant alleles.
The planets in our Solar System formed from the solar nebula – the disc of gas left over from the formation of our Sun. ... The gas giants on the other hand, formed far enough away from the Sun that the temperature was cool enough for these volatile gases to condense, and form these huge, less dense planets
Cells got their name from an Englishman named Robert Hooke in the year 1665. He first saw and named "cells" while he was experimenting with a new instrument we now call a "microscope."
Answer:
The most abundant gas in the atmosphere is nitrogen, with oxygen second, and argon as third.
Explanation:
The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. The gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Usually, the 4 most abundant gases are:
Nitrogen (N2) - 78.084%
Oxygen (O2) - 20.9476%
Argon (Ar) - 0.934%
Carbon dioxide (CO2) 0.0314%
