- man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give the genotypes and phenotype of offspring.In dogs, rough hair (R) is dominant to smooth hair (r). If you crossed a homozygous, rough hair dog with a smooth hair dog, what would be the phenotype(s) of the offspring? Half the offspring would have rough hair and half would have smooth hair They would all have rough hair They would all have smooth hair O There is no way to tell from the information givenIn cattle, coat color is inherited in a co-dominant fashion. Homozygous C R C R produces red coat,homozygous C W C W produces white coat, and the heterozygous C R C W produces roan-colored coat.What is the probability of having a roan-coated offspring in a cross between a white-coated cattle anda roan-coated cattle?
- In the example below, crossing you left thumb over your right thumb is dominant T to crossing your right over left recessive t. Identify the genotype of the individual shown below: OShutterstock / robynleig O A. homozygous dominant (TT) O B. heterozygous dominant (Tt) or homozygous dominant (TT) OC. homozygous recessive (tt) O D. Cannot be determined from information providedIn humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. Draw the Punnett square that illustrates this marriage. What is the man’s genotype? What are the genotypes of the children?A litter of cats has two black and two white kittens. The mother is white and you know that in cats black fur is dominant.

- In humans, having freckled skin (F) is dominant. Assume that a homozygous recessive man and a heterozygous woman have a child. a. What is the woman's phenotype? b. Show the Punnett square for the cross. С. What is the child's probability of having no freckles? UuntIn humans, Widow’s peak (W) is dominant over a continuous hairline (w), and short fingers (F) are dominant over long fingers (f). Two individuals with widow’s peaks and short fingers have a child with a continuous hairline and long fingers. Determine the genotype of the parents.In cats, short hair (L) is dominant over long hair (l) and stripes (A) are dominant over solid color (a). A cat with genotype Ll Aa mates with a cat that is Ll aa, and they produce a litter of six kittens. What is the probability that four of the six kittens will have both long hair and stripes?
- You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob. Crossing the plant with heterozygous purple flowered pea plant (Pp) Crossing the plant with homozygous dominant purple flowered pea plant (PP) d. Crossing the plant with a plant whose genotype is unknown e. Crossing the plant with homozygous recessive white flowered pea plant (pp)In mice, the A allele causes agouti fur, the AY allele causes yellow fur and is dominant to the A allele. The homozygous AY AY genotype is lethal. Why is the AYAY homozygous condition lethal?In certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?
