Aplant can produce either purple flowers or white flowers. what is the probability of purple-flowered offspring if two plants that are heterozygous for purple flowers are crossed? a. 1: 4 b. 2: 4 c. 3: 4 d. 4: 4

The answer is C. 3:4. Let allele A be dominant allele for purple flowers and allele a be recessive allele for white flowers. Heterozygotes (Aa) will have purple flowers because they have one dominant allele. In their cross: Aa x Aa, the offsprings will be: AA, Aa, Aa, aa. So, purple flowers will be AA, Aa, and Aa, which are 3 out of total 4 flowers. In other words, the probability is 3:4.

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.
