The gene for flower color in snapdragons displays incomplete dominance. Snapdragons homozygous for the allele for red flower color have the genotype FRFR and have red flowers. Snapdragons homozygous for the allele for white flower color have the genotype FWFW and have white flowers. Heterozygous snapdragons, with the genotype FRFW, have pink flowers. A snapdragon that has pink flowers is crossed with a different snapdragon that has pink flowers. What percentage of the offspring is expected to have red, white, and pink flowers?

In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
For some traits, one allele is not completely dominant to another. Incomplete dominance occurs when neither allele dominates over the other. The resulting phenotype of heterozygotes is an intermediate of the two extremes. Incomplete dominant genes control snapdragon flower color. Red flower plants crossed with white flower plants produce offspring with pink flowers. One human trait that is thought to be inherited in this fashion is hair structure. Curly hair and straight hair are due to homozygous genotypes and wavy hair is produced by the heterozygous genotype. An incompletely dominant gene also controls the plumage of chickens. Black plumage and white plumage are due to homozygous genotypes and a blue-grey color results from a heterozygous genotype. Using Punnett squares and variations of the letter “B”, answer questions 1-3 and use variations of the letter “R” to answer questions 4-5. What type of offspring and in what ratio would you expect from a cross between a black…
There is a species of fish in which homozygous recessive (rr) individuals are Yellow and homozygous dominant (RR) individuals are Red. Color in this species of fish exhibits incomplete dominance. If we mate a homozygous dominant individual with a heterozygous individual, what is the phenotypic ratio of the offspring? Group of answer choices 2 Red : 2 Orange. 4 Red. 3 Red : 1 Yellow. 1 Red : 2 Orange : 1 Yellow.
In pea plants, tall (T) is the dominant allele in plant height over short (t) and the yellow color allele (Y) is dominant over the green color allele (y) for seed color. Parents heterozygous for both traits are cross-pollinated. Determine the frequency for the four different phenotypes of the offspring. Tall plant, yellow seeds: __________ / 16 Tall plant, green seeds: _________ / 16Short plant, yellow seeds: _________ / 16 Short plant, green seeds: _______ / 16 Pure-breeding yellow (Y) canaries (a canary is a type of bird) crossed with pure-breeding blue (y) canaries make green canaries. Identify the genotypic and phenotypic ratios when you cross a green canary with a blue canary. What type of inheritance pattern is this? _______________________________________________ Genotypic Ratio: _________________________________ Phenotypic Ratio: ________________________________
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. Trait Dominant Recessive Pod color Yellow Green Pea shape Round Wrinkled A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? a) 1/2 b) 1/4 c) 1/8 d) 1/16
In rabbits, full coat color (C) is the dominant trait. A second allele, chinchilla (cch) is recessive to full coat color. Himalayan coat color (ch) is recessive to chinchilla and full coat colors, and albino (c) is recessive to all coat colors. If two heterozygous Himalayan rabbits mate, what is the expected phenotypic ratio in their offspring? 3 Himalayan : 1 albino 3 Himalayan : 1 chinchilla 2 Himalayan : 2 albino All Himalayan Cannot be determined from the information given
In canaries, feather length is determined by a sex-linked gene at the G locus with two alleles. The wild-type allele produces long feathers while thedominant allele results in short feathers. An autosomal locus determines feather density (called plumage) where the dominant A allele causes denseplumage. A long-feathered female with thin plumage mates with a male that has short feathers and a dense plumage. Their first chick is a female with longfeathers and thin plumage. a) What is the genotype of the male parent in this cross? b) If the next chick is a male, what is the probability of him having short feathers and thin plumage? c) A chick is caught that is pure-breeding for long feathers and dense plumage. However, you believe this chick was not from these parents. Provide areason that supports your idea.
Which example correctly reflects co-dominance and incomplete dominance? A Codominance - blood type A, in a person carrying allele A and allele O, and A is dominant to O; only antigen A is expressed on red blood cell surface of people with IAi genotype.Incomplete dominance - red and white flower color inheritance of snapdragons, where the heterozygotes show both, red and white phenotype simultaneously (patchy appearance of the flower petals). B Codominance - blood type AB, where antigen A is dominant to B; only antigen A is expressed on red blood cell surface of people with IAIB genotype.Incomplete dominance - red and white flower color inheritance of snapdragons, where the heterozygotes show red phenotype. C Codominance - blood type AB, where antigen B is dominant to A; only antigen B is expressed on red blood cell surface of people with IAIB genotype.Incomplete dominance - red and white flower color inheritance of snapdragons, where the heterozygotes show white phenotype.…
In a species of dog, plaid color is represented by P and purple by p, short -tailed is T and long-tailed is t. What are the genotypes of a male who is purple with a long tail, and a female who is homozygous dominant for both traits? Which answer below is true? PpTT & PPTT pptt & PPTT short-tailed purple & long tailed plaid male: purple w/ long tail & female: plaid w/ short tail
Two pair of alleles are known to interact in the production of feather color in parakeets. Allele B is needed for Blue pigment, whereas the recessive “b” resulted in lack of color. The dominant C is associated with yellow pigment whereas the recessive allele “c” also resulted in lack of color. Blue and Yellow pigments together produce green feather color. Give the genotype of each of the following A green bird that has a white off spring A yellow bird that has a green parent A blue bird that has two parents A white bird that had a green parent and a blue parent.
In cats, the locus for orange coat color is sex linked. Male cats that are black have the o+ allele, whereas those that are orange have the o allele. Females can be homozygous for the orange allele or homozygous for the black allele and will express each color, respectively. Heterozygous females are tortoise-shelled or calico, having orange and black patches. A calico cat, in addition to being heterozygous at the orange locus, also is either heterozygous or homozygous for the incompletely dominant, autosomal spotting allele (SS = large spots, Ss = small spots, ss = no spots). Manx tails are caused by a dominant trait that is lethal when homozygous. Long tails are the result of a homozygous recessive genotype. An orange male with small white spots and a manx tail is crossed to a calico female with small white spots and a manx tail. What is the probability of observing a solid black female with no spots and long tail? (Hint: All calico cats are female!)
In humans, there are tree alleles for blood type: A, B, and O. The allele for blood type A and the allele for blood type B show incomplete dominance. A person with both alleles has blood type AB. Both A and B dominate type O. A person with alleles for blood types A and O marries someone with alleles for blood type B and O. List the types of blood their offspring could have and the probability for each blood type in the offspring.
