Many farmers prefer cattle without horns because it is safer for their herds. The allele for no horns (N) is dominant to the allele for the presence of horns (n). A farmer mates a male with horns to a heterozygous female without horns. What is the chance that the offspring will have horns? Construct the punnet square Parents’ genes? Parents’ traits? Genes (genotype)? Horn (phenotype)? Genotypic ratio? Phenotypic ratio?

In some bizarre-feathered chickens, F is the trait for frizzled feathers while S is the trait for straight feathers. Since both traits are appears to be dominant, what proportion of the offspring would likely show straight feathers? Construct the punnet square and indentify the following: Parents’ genes? Parents’ traits? Genes (genotype)? Feather type? (phenotype)? Genotypic ratio? Phenotypic ratio?
A gardener received a pea plant from her neighbor, and she wants to know its genotype. The neighbor told her it produces round peas, which is a dominant trait (R) to wrinkled peas (r). The gardener performs a test cross and observes that half of the offspring plants produce wrinkled peas. What is the genotype of the plant she received from her neighbor?) homozygous recessive, rr heterozygous, Rr homozygous dominant, RR In pea plants, the allele for round peas (R) is dominant to the allele for wrinkled peas (r). A gardener has a plant he got from his neighbor that produces round peas, but he does not know its genotype. What simple procedure could he do to determine the genotype of his new plant?) Perform a dihybrid cross—if only 1 out of 16 offspring are wrinkled, then the new plant’s genotype is RR. Perform a test cross with a plant that has an Rr genotype—if all of the offspring give round seeds, then the new plant’s genotype is Rr. Perform a test cross…
In horses, the allele for straight hair (H) is dominant, and the allele for curly hair (h) is recessive. A horse breeder mates a homozygous dominant mother with a heterozygous male. Construct the punnet square Parents’ genes? Parents’ traits? Genes (genotype)? Hair type (phenotype)? Genotypic ratio? Phenotypic ratio?
In a certain breed of dogs, a gene (L) codes for hair length. The dominant trait is short hair and the recessive is long hair. Suppose a heterozygous female dog and a homozygous recessive male dog mate. What is the male dog’s genotype and the female dog’s genotype? What is the male dog’s phenotype and the female dog’s phenotype? What will be the genotypic ratio for the offspring from these dogs? What will be the phenotypic ratio for the offspring from these dogs?
In Vulcans, black hair and pointy ears are dominant traits. Pollar has black hair but rounded ears. Damak, his mate, has red hair and pointed ears. Their first child, T’Pal, has red hair and rounded ears. Their second child, Spock, has black hair and pointed ears. Use EE or Ee for pointed ears and BB or Bb for black hair and answer the following: What is Pollar’s genotype? Group of answer choices a. BbEe b. Bbee e. BBee d. BBEe
Consider a greenhouse with 500 carnation plants. 280 plants are homozygous for the red allele (RR), 120 plants are heterozygous (Rr), and 100 plants are homozygous for the white allele (rr). What is the frequency of the red allele? What is the frequency of the white allele?
Brown fur vs white fur. Say that the alleles for fur color (brown or white) are written using the letter “B” and “b”. The dominant trait is brown, white fur color represents the recessive trait. How would you write out a homozygous dominant individual?

A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotypre is .35 What is the frequency of the heterozygous rabbits? What is the frequency of the B allele? What is the frequency of the b allele?
Which of the following statements is/are false regarding alleles? (Select all correct answers.) For a given species, every gene has only two alleles All disease causing alleles are recessive to the wild-type allele A single allele can be recessive to the wild-type allele for one phenotype, but dominant to the wild-type allele for a different phenotype. For any pair of alleles of a given gene, the same dominant/recessive relationship will be found for all phenotypes affected by that gene
Rather than studying you are watching Maury. A couple comes on with a baby The father has brown eyes, his parents, grandparents, sister, and brothers all have brown eyes. The mother has blue eyes and the baby has blue eyes. The brown eye allele is dominant to blue eye allele. Using this information, answer the following question? Based on the Punnett Square, what are the chances that these are the parents of the child?
Say you have a lab population of 1000 dragonflies that is in Hardy Weinberg equilibrium. Body color is determined by a single gene with 2 alleles. The white body color phenotype is due to the homozygous recessive phenotype. Out of the 1000 dragonflies, 250 are white. Heterozygous and homozygous dominant individuals are green. How many of the 1000 dragonflies are heterozygous? Group of answer choices 25 250 500 50 125
