1. In silkworms, a PURPLE cocoon is dominant over a BLUE cocoon. Cross a homozygous purple silkworm with a homozygous blue. List genotypes and phenotypes. 2. In guinea pigs, short fur is dominant over long fur. Cross a heterozygous female with a homozygous long furry male. List genotypes and phenotypes.

3.In race horses, black coat (B) and trotting gait (T) are dominant traits. Recessive traits are chestnut coat (b) and pacing gait (t). Use a Punnett square to determine the possible offspring from a cross between a heterozygous black coat trotter and one that is homozygous for black coat and is a pacer. List genotype and phenotype ratios.

4.In pea plants, a YELLOW (Y) color is dominant over PURPLE (y) and SMOOTH (S) is dominant over WRINKLED (s). Use a Punnett square to determine the F2 generation from a cross between a homozygous yellow smooth pea and a heterozygous yellow smooth pea. List the genotype and phenotype ratios.

Which of the following is an example of this type of co-evolution

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
