quick: having straight ears (e) is dominant over having
droopy ears (e). a parent with straight ears is crossed
with a parent with droopy ears. the punnett square
shows the possible genotypes of the offspring.
what is the probability that an offspring will have a
heterozygous genotype?
what is the probability that an offspring will have a
homozygous dominant genotype? %
what is the probability that an offspring will have a
homozygous recessive genotype? %

50%, 0%, 50%

Explanation:

From the Punnet square, there are 2 heterozygous genotypes out of 4 offspring, hence, the probability that an offspring will have a heterozygous genotype is 1/2 or 50%.

There are no homozygous dominant genotype among the genotype of the offspring as seen in the Punnet square. Hence, the probability of an offspring having a homozygous dominant genotype id 0%.

There are 2 homozygous recessive genotype out of 4 genotype of the offspring, hence, the probability of an offspring having a homozygous recessive genotype is 1/2 or 50%.

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
