A population of white leghorn chicken has the following dominant mutations: crested head, the condition of having elongated feathers on the crown of the head, is dominant to normal-feathered head naked neck, the condition having no neck feathers, is dominant to normal-feathered neck Both are unlinked autosomal genes. A rooster is heterozygous for both of these traits. It mates with a hen that is also heterozygous for both traits. What is the percentage of their offspring that are predicted to have a normal-feathered head and naked neck? (Round your answer to one decimal place). For full marks, your work must be clearly shown

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?
In birds there are two genes that both influence feather phenotype. The first is an autosomal gene for feather shape with two alleles – a dominant allele for curly feathers and a recessive allele for straight feathers. The second is a sex-linked gene for feather colour with two alleles – a dominant allele for grey feathers and a recessive allele for white feathers. A cross between a male with straight, white feathers and a female with curly, grey feathers are expected to produce the following offspring:1 curly grey male : 1 curly white female : 1 straight grey male : 1 straight white female Based on this cross, answer the following questions:i) Please provide appropriate symbols for the two alleles for feather shape. ii) Please provide appropriate symbols for the two alleles for feather colour. iii) What is the probability that a chick born to these parents will have grey feathers? iv) What is the probability of a male chick having grey feathers? v) What is the probability that this…
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.
Sometimes, two alleles are neither dominant nor recessive, therefore, both alleles are expressed separately in a heterozygous individual. This is called codominance. Which of the following is an example of codominance? a In guinea pigs, black hair is dominant over white hair. A homozygous black guinea pig is crossed with a homozygous white guinea pig. The first generation of offspring are black. b If you cross a plant with blue flowers with a plant with yellow flowers, the offspring will have blue flowers with yellow spots. c If you cross a rhododendron plant with red flowers with a rhododendron plant with white flowers, the offspring will have pink flowers. d A white female cat mates with a brown male cat. The resulting offspring are orange.
In genetics, the dash symbol (–) is a “wild card” that stands for either the dominant allele or the recessive allele; for example, A– means the individual has either the genotype AA or Aa. Two genes that undergo independent assortment affect coat color in Duroc pigs. Each gene has two alleles, one of which is dominant for coat color. Genotypes of the form A– B– are red, those of the form A– bb and aa B– are sandy, and genotype aa bb is white. What ratio of red:sandy:white is expected from the cross Aa Bb x Aa Bb?
Tightly curled hair is caused by a dominant autosomal gene in humans. This trait is rare among northern Europeans. If a curly-haired northern European marries a person with straight hair, what phenotypes (and in what proportions) are expected in the offspring? A. ½ curly (because the curly-haired individual is most likely heterozygous), ½ straight B. ½ curly (because the curly-haired individual is most likely homozygous), ½ straight hair C. all curly (because the curly-haired individual is most likely heterozygous) D. ¾ curly (because the curly-haired individual is most likely heterozygous), ¼ straight hair E. None of the choices that are provided is correct
A scientist is investigating the inheritance of two autosomal recessive genes in rat, ear length (long is dominant to short) and fur color (gray is dominant to white). The table below provides the number of observed off-spring for each phenotype, when heterozygous rats are crossed. What are the expected values for each phenotype? Phenotype Observed Expected Long, gray 189 Long, white 56 Short, gray 74 Short, white 23 Total 342
In a mating between two individuals that are heterozygous for a recessive lethal allele that is expressed in utero, what genotypic ratio (homozygous dominant:heterozygous:homozygous recessive) would you expect to observe in the offspring? a. 1:2:1 b. 3:1:1 c. 1:2:0 d. 0:2:1
A sex-influenced trait in humans affects the length of the index finger. A short allele is dominant in males and recessive in females.Heterozygous males have an index finger that is significantly shorterthan the ring finger. The gene affecting index finger length is locatedon an autosome. A woman with short index fingers has childrenwith a man who has normal index fingers. They produce five children in the following order: female, male, male, female, male. Theoldest female offspring has one daughter with a man who has normal fingers. The youngest male among the five children has childrenwith a woman with short index fingers; they have two sons. Drawthe pedigree for this family. Indicate the phenotypes of every individual (filled symbols for individuals with short index fingers andopen symbols for individuals with normal index fingers)
In dogs, albino white coat color is an autosomal recessive trait, while black coat is a dominant trait. Homozygous recessive mutations in at least two different genes have been reported to cause white coat color in poodles. A woman owned a purebred albino female poodle. The woman wanted to have more white poodle puppies. She took her dog to a breeder, who promised her to mate the woman’s purebred albino female poodle with a purebred albino stud male. When six puppies were born, all of them were black. The woman sued the breeder, claiming that the breeder failed to breed her poodle with a purebred albino stud male but with a black dog, giving her six unwanted black puppies. You are called in as an expert witness. Based on your knowledge in genetics, which of the following explanations for the case would you consider to be the most reasonable to offer to the court? Question options: To determine if the breeder is innocent, the court needs to separately breed the…
In mice, the presence of AA alleles give rise to the agouti fur color, AAY gives rise to a yellow fur color, and AYAY is lethal, causing mice to die before birth. The B allele results in pigment formation and is dominant over the b allele. The bb genotype results in no pigment formation and gives an albino fur color irrespectively of the presence of the AA or AAY alleles. In the following cross between a yellow and agouti mice, what would be the expected proportion of agouti fur mice among the live offspring? AAY Bb X AA Bb 1/2 1/4 3/8 1/3 3/4
Albinism is the absence of pigment throughout the body. Animals with albinism have white fur and reddish eyes. Albinism is inherited as a recessive trait, so animals with two a alleles have albinism, whereas animals with at least one dominant A allele have normal coloring. Using the Punnett square below, determine the probability of two albino parents (with aa genotypes) producing a child with albinism.
