Q1. What is the difference between incomplete dominance and codominance? A. In incomplete dominance, the dominant phenotype is expressed in heterozygotes. In codominance, both phenotypes are expressed in heterozygotes. B. The phenotype reveals the genotype only in codominance. C. In both types of inheritance, the heterozygotes express the phenotypes dictated by both alleles. D. In codominance, both phenotypes are expressed in heterozygotes. In incomplete dominance, the heterozygote shows a phenotype that is intermediate between the two homozygotes. Q2. Based on...
Which of the statements about incomplete dominance are true? 1) Heterozygous individuals have the same phenotype as homozygous dominant individuals. 2) Heterozygous individuals have a phenotype intermediate to the homozygous dominant and homozygous recessive phenotypes. 3) Heterozygous individuals express both the homozygous dominant and homozygous recessive phenotypes. 4) If homozygous dominant mice have black fur, and homozygous recessive mice have white fur, then heterozygous mice have gray fur.
6. (10 points) For traits that show incomplete dominance, describe the phenotype of the heterozygote.
In a gene with incomplete dominance for petal color, there are 2 possible alleles: Ar (codes for red petals) and Aw (codes for white petals). The heterozygote codes for pink petals. In the population, there are 500 red individuals, 250 pink individuals, and 250 white individuals. a) What is the frequency of each phenotype? b) What is the frequency of each genotype?
0.33334 points QUESTION 62 Horse coat follows incomplete dominance: DD - chestnut (dark brown); D101 = pale cream; and DD1 -palomino. If a male and female palomino mate what is the probability of offspring genotypes and phenotypes? both 1:2:1 both 3:1 1:2:1 genotyke: 3:1 phenotype 3:1 genotype; 1:2:1 phenotype
18. Coat color in shorthorn cattle is determined by incomplete dominance. Individuals homozygous for the red allele (CRC) have red fur, individuals homozygous for the white allele (CWCW) have white fur, and heterozygous individuals (CCW) are roan (brown and white). A second gene in these cattle determines if they will have horns. The horned allele (H) is dominant to hornless (h). Predict the genotypic and phenotypic ratios of the offspring if a heterozygous horned-roan bullis crossed with a hornless -...
What can explain the phenomenon where the same genotype might give rise to different phenotypes? A. codominance B. pleiotropy C. complete dominance D. recessive lethal E. Incomplete dominance

8. Pea plant breeders wanted to pick healthy tall plants that were homozygous for the height gene. They had a collection of 10 plants that were healthy and tall, but the genotypes were unknown. How might they determine if the 10 tall plants were heterozygous or homozygous for the height gene? a. What genotypes are possible for tall pea plants? b. What cross would be most useful in distinguishing between homozygous and heterozygous tall plants? c. Explain the concept of...
Question 1 (30 points) Suppose a lizard species demonstrated incomplete dominance for its skin color. A homozygous individual (BB) would be blue. A homozygous (bb) individual would be red. A heterozygous (Bb) individual would be purple. What would be the phenotypes (skin color) and the genotypes (alleles: BB, Bb, bb) for the offspring of a blue lizard crossed with a red lizard? You can use a Punnett square to figure out the answer, but you don't need to include a...
