Scenario: A plant species has flowers that can be red, pink, or white. Flower color is controlled by one gene with two alleles, A (p) and a (q). Red flowers are produced by AA homozygotes, pink flowers are produced by Aa heterozygotes and white flowers are produced by aa homozygotes. A recent survey of 100 of these plants found the following number of different flower colors: 75 plants with red flowers, 20 pink flowers, 5 white flowers. What are the observed genotype frequencies in this population?
You are studying three traits in a goldfish variety; body colour (A or a), tail length (B or b) and shape (C or c). Note: Use the uppercase letters for the alleles associated with the dominant phenotypes and the lowercase letters for the alleles associated with the recessive phenotypes. Assume that each of these traits is regulated by one gene. a) You mate a gold fish (P1) with a white fish (P2) and obtain 100 fish in F1, of which 50 are gold and 50 are white. Write two sets of the possible genotypes of the parental and the resulting F1 fish

In a species of beetles, individuals may be red, black, white or tan. Colour is controlled by a single gene with multiple alleles in a dominance series. Red (R) is dominant to black (Rb), black is dominant to white (Rw) and white is dominant to tan (r) (R > Rb > Rw > r).Colour variation in this species is a female sex-limited trait. Males carry the colour genes but are always phenotypically tan regardless of their genotype.What are the genotypes of the parents of the following cross? white female × tan male produce 13 red females: 6 white females: 5 tan females: 19 tan males
In rural northeast Kansas domesticated cats are becoming wild, and biologists are observing that wildcats occur in three colors. Fur color is controlled by a single gene that exhibits incomplete dominance. A homozygous dominant cat is blue (BB), a homozygous recessive cat is red (bb), and a heterozygous wildcat will be purple (Bb). What would be the expected phenotypes of the offspring if a blue wildcat mates with a red wildcat? Develop a Punnett square and list the genotypes as well.

What are the expected genotype frequencies in this population under Hardy-Weinberg?
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 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
EXAMPLE PROBLEM Two black female mice are crossed with a brown male. In several litters, female I produced 9 black offspring and 7 brown; female II produced 57 black offspring. What deductions can you make about the inheritance of black and brown coat color in mice? What are the genotypes of the parents? Dominance and recessive describe which of two possible phenotypes are exhibited when two different alleles occur in the same individual.
Black coat colour in cocker Spaniels is governed by a dominant allele B and red coat colour by its recessive allele b; solid pattern is governed by the dominant allele of an independently assorting locus S, and sported pattern by its recessive allele s. A solid black male is mated to a solid red female and produces a litter of six pups: two solid black, two solid red, one black and white, and one red and white. (a) What are the possible genotypes of all the phenotypes obtainable? (b) Determine genotype of the parents. Hint- an unknown portion of a genotype may be indicated by a dash (-).
In a complete dominance system: A certain dominant gene causes some people in the population to be born with 6 fingers (F) instead of 5 (f). Another dominant gene causes dwarfism (D) while normal height (d) is recessive. A father, Darren, has five fingers and is of normal height. The mother, Morgan, has 6 fingers and is also a dwarf although her mother is of normal height and has 5 fingers. What percent of the offspring will have dwarfism and have 6 fingers?
In skunks, black and white stripes (S) are dominant and black and white spots (s) are recessive, and red eyes (R) are dominant to brown eyes (r). Both traits are independent. You cross a male skunk with black and white spots and brown eyes to a female with black and white stripe and red eyes. They have three babies: (1) A male with stripes and brown eyes; (2) A female with stripes and red eyes; (3) A female with spots and red eyes. What is the genotype of the female skunk?
