A true-breeding black coat colour of a breed of dog was crossed with a true-breeding brown coat colour. The F1 progeny were all black coat colour. When the F1 offspring were crossed, 103 of the F2 offspring had black-coat colour and 38 brown-coat colour. State the genetic basis of this inheritance.

The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
In a parental cross of a ADHL disease trait, where the father is affected and the mother is unaffected, 50% of the offspring will have the disease phenotype and 50% will have the WT phenotype. In an F1 cross between an affected male and an affected female, the respective proportions of the disease phenotype and WT phenotype are:
In pea plants, flower color is determined by one gene with two alleles, with the allele coding for purple flowers (P) being dominant to the allele coding for white flowers (p). If two purple-flowered offspring resulting from a cross between homozygous dominant and white-flowered parents are crossed, what percentage of the progeny are expected to have the dominant phenotype?
In a parental cross of a autosomal dominant homozygous lethal disease trait, where the father is affected and mother unaffected, 50% of offspring will have disease phenotype and 50% will have the wild type phenotype. In f1 cross between affected male and unaffected female, the expected proportions of the disease phenotype and the wild type phenotype in the f2 generation are:
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited?
In horses, coat color comes in many varieties. If a brown horse is crossed with a white horse, the offspring are palominos (brown and white manes and tails). Name the type of inheritance. If a palomino horse is crossed with a white horse, what will the phenotype ratio of the F1 be?
In a certain animal, black coat (B) are dominant to white coat (b). In a genetic cross of two animals that are heterozygous for coat color, what is the probability of having white coat? Write in fraction form
In dogs, black (B) is dominant over brown (b) color. What would be the color of the puppies if a purebred black dog is crossed with a purebred brown dog? What would be the phenotypic ratio of the F1 offspring? Show a punnet square for this cross
In guinea pigs, black hair color (B) is dominant and brown hair color (b) is recessive. Long hair (L) is dominant and short hair (l) is recessive. Answer the following questions: a) Diagram the complete cross: BBLL x bbll b) What are the genotypes and phenotypes of the F1 generation?
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream-colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited? _______________ Identify the genotype of the white guinea pig. ________ Identify the genotype of the yellow guinea pig. ________ Identify the genotype of the cream-colored guinea pig. ________ Identify the genotypes and the corresponding phenotypes of the F2 progeny. Give the genotypic ratio. __________________ Give the phenotypic ratio. ___________________
