 1 One cat carries heterozygous, long-haired traits (Ss), and its mate carries homozygous short-haired traits (ss). Use a Punnett square to determine the probability of one of their offspring having long hair. A) 75% B) 25% C) 50% D) 100% 2 One cat carries heterozygous, long-haired traits (Ss), and its mate carries homozygous short-haired traits (ss). Use a Punnett square to determine the probability of one of their offspring having short hair. A) 50% B) 25% C) 75% D) 100% 3 One flower is heterozygous red (Rr) and it is crossed with a homozygous white (rr) plant. Use a Punnett square to determine the probability of one of their offspring having a red color. A) 25% B) 50% C) 75% D) 100% 4 One flower is heterozygous red (Rr) and it is crossed with a homozygous white (rr) plant. Use a Punnett square to determine the probability of one of their offspring having a white color. A) 75% B) 25% C) 50% D) 100% 5 In a certain species of plant, the color purple (P) is dominant to the color white (p). According to the Punnett Square, what is the probability of an offspring being white? (1.0K) A) 100% B) 25% C) 75% D) 0% 6 In a certain species of plant, the color purple (P) is dominant to the color white (p). According to the Punnett Square, what is the probability of an offspring being purple? (1.0K) A) 100% B) 0% C) 25% D) 75% 7 In a certain species of plant, the color purple (P) is dominant to the color white (p). According to the Punnett Square, what is the probability of an offspring being white? (1.0K) A) 100% B) 50% C) 75% D) 25% 8 In a certain species of plant, the color purple (P) is dominant to the color white (p). According to the Punnett Square, what is the probability of an offspring being purple? (1.0K) A) 50% B) 25% C) 75% D) 100% 9 In a certain species of pine trees, short needles (S) are dominant to long needles (s). According to the Punnett square, what is the probability of an offspring having short needles? (1.0K) A) 50% B) 25% C) 75% D) 100% 10 In a certain species of pine trees, short needles (S) are dominant to long needles (s). According to the Punnett square, what is the probability of an offspring having long needles? (1.0K) A) 25% B) 50% C) 75% D) 100%
