From the parent with genotype Aa, what is the best prediction of the gametes? A.100% of the gametes will carry a dominant allele, b. Every gamete will have both the A and the a allele, c.50% of the gametes will carry a dominant allele, 50% of the gametes will carry a dominant allele, d.75% of the gametes carry neither the A or the a allele

50% will carry a dominant allele

Explanation:

There are only two possibilities, A or a

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
