- One of the coat color patterns in cats is determined by a pair of codominant alleles located onthe X The allele (B) produces black color, and its allele (B') produces yellow color.The heterozygote (BB') has a tortoise-shell pattern. Determine the genotypic and phenotypic frequencies expected from a cross between a black male and yellow female. Determine the genotypic and phenotypic frequencies expected from a cross between a black male and tortoise-shell female.In cat, a black cat when crossed with a white cat produces a tabby which appears to be a gray cat striped with black and white fur. What is the F1 phenotyphic ratio of a cross between a black and white cats? Numerical anwers only. When tabby cats are crossed with black cat. what is the phenotypic ratio of the offspring? Numerical anwers only. When tabby cats are crossed black cat. What is the phenotypes of the offspring? write in CAPITAL LETTERS WITH SEPARATE COMMAS When tabby cats are crossed with white cat. what is the phenotypic ratio of the offspring? Numerical anwers only. What is the specific mode of inheritance behind this phenomenon?In guinea pigs, short hair is dominant to long hair. Also in guinea pigs, black eyes aredominant to red eyes. A male guinea pig that is heterozygous for both traits is crossedwith a female that is long haired and red eyed. What are the expected phenotypes oftheir offspring? Provide the phenotypic ratio as well.
- Rabbit fur is determined by multiple alleles. Solid color is controlled by the Ic allele, the chinchilla by the Ich allele, the Himalayan by Ih and the albino by i. The dominance hierarchy of these alleles is Ic> Ich> Ih> i. Write the gametes that a HIMALAYAN rabbit would form [x1]Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced. What is the percent probability of obtaining a yellow or blue parakeet when a heterozygous green parakeet is crossed with a white parakeet? Show all work including Punnett square and explanation. Record your answer as a whole number rounded to one decimal place.A wild-type fruit fly (heterozygous for gray body color andred eyes) is mated with a black fruit fly with purple eyes. Theoffspring are wild-type, 721; black purple, 751; gray purple, 49;black red, 45. What is the recombination frequency betweenthese genes for body color and eye color? Using informationfrom problem 3, what fruit flies (genotypes and phenotypes)would you mate to determine the order of the body color, wingsize, and eye color genes on the chromosome?
- In rabbits, black fur (F) is dominant to white fur (f). You decide to cross a rabbit that is homozygous dominant for fur color with a rabbit that is heterozygous for fur color. Set up a Punnett Square for this cross and then answer the following questions. What percentage of offspring will have the [ Choose ] FF phenotype? What percentage of offspring will have the ff [ Choose ] phenotype? What percentage of offspring will have the Ff [ Choose ] phenotype? > > >pure-breeding yellow (Y) canaries crossed with pure breeding blue (y) canaries make green cancaries. identify the genotypic and phenotypic ratios when you cross a green with a blue. what type of inheritence pattern is this?The narrow-sense heritability of the number of peas perpod in a population of sugar snap peas is 0.5. The meanof the population is 6.2 peas per pod. A plant breederselects one plant with 6.8 peas per pod and crosses witha second plant that has 8.0 peas per pod. What is the expected numbers of peas per pod among the offspring ofthis cross?
- The dominant white allele (W) is a homozygous lethal and is dominant over the full color allele (w) in horses. The “overo” paint-spotting allele (O) is also lethal when homozygous and it is dominant over the nonspotting allele (o). The dominant at the white locus, however, masks the paint phenotype. Two horses of the genotype WwOo are crossed. At what frequency is a full color (not painted and not white) horse expected from this cross?Heterozygous Cc chickens express a condition called creeper, in which the leg and wing bones are shorter than normal (cc). The dominant C allele is lethal when homozygous. Skin color is determined by the alleles W and w. W_ chickens have white skin and ww chickens have yellow skin. In a mating between 2 chickens heterozygous for both of these genes: 1) What phenotypes will be observed in the progeny? 2) What fraction of the offspring will have each phenotype? Assign alleles. List possible phentoypes. Make gametes, draw Punnett square, and list fractions of genotypes and/or phenotypes of offspring,"In summer squash fruit color is determined by two loci. Yellow is dominant to green. White fruits are produced by the dominant epistatic allele W at a separate locus. If two white fruit bearing plants, heterozygous for both traits are crossed, what ratio will be observed in the next generation?"
