A red animal (AA dominant) mates with a yellow animal (aa recessive). What would be the genotype and phenotype of a heterozygous offspring? (Assuming complete dominance)
a. phenotype (yellow): genotype Aa
b. phenotype (red); genotype AA
c. phenotype (yellow); genotype aa
d. phenotype (red): genotype Aa

d.phenotype red: genotype Aa

Explanation:

a red animal that is a Donna Mae a would still have dominance over the yellow animal it recessive so if you put it in the chart form AA would be on top and the lowercase a a would be on the left side so it would be phenotype red genotype capital a lowercase a .

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.

idk im sorry.
