Suppose that a dominant allele (p) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. if two heterozygous individuals with polka-dot tails mate, what's the probability of the phenotype and genotype combinations of the offspring? a. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (75 percent pp; 25 percent pp) b. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail c. 25 percent chance of a polka-dot tail and 75 percent chance of a solid colored tail d. 50 percent chance of a polka-dot tail and 50 percent chance of a solid colored tail

The correct answer is B. This question relates to using a punnet square to determine the genotypes of the offspring. Two heterozygous parents expressing a polka-dot tale must have genotype Pp each. 

Using a punnet square, this will produce 4 possible genotypes in equal probability:
PP - polka dot
Pp - polka dot
Pp - polka dot
pp - solid tale

Therefore there is a 75% change of getting polka dots in the offspring, and a 25% chance of solid tale.

A. is an incorrect answer because only 50% of offspring will be type Pp, another 25% will be expressing double dominant alleles for P as PP, which will still express polka dots.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.

Humans can affect weathering and erosion in several ways.  humans cause  increases in acid rain and pollution, which increase the amount of  weathering  agents in the air and water, and then on land.for an easy answer: 1) acid rain2) pollution
