Labradoodles are a designer dog "breed" created from the mating of a poodle with a Labrador retriever. In the first generation, labradoodles can have straight, wavy, or curly hair that is thought to be governed by two alleles at a single gene locus that show incomplete dominance. Dogs homozygous for the allele have straight hair, those homozygous for the C allele have curly hair, and heterozygotes have way hair. A labradoodle breeder has collected records for the last 10 years covering 1000 first- generation puppies. In total, 190 straight hair, 480 wavy hair, and 330 curly hair puppies were adopted. a) Calculate the frequencies of the S (p) and C(q) alleles in this population. Round your calculated frequencies to 2 decimal places. p= 1.0 q= b) The breeder suspects that her clients prefer to adopt the curly haired puppies because they are cuter. Determine whether her suspicions are correct by calculating whether the actual numbers adopted puppies for each phenotype are reflective of their expected numbers if this samples was in Hardy-Weinberg equilibrium. Enter expected numbers rounded to one decimal place. Expected number of straight-hair puppies:

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?
A genetic engineer is going to cross two watermelon plants to produce seeds for a spring planting. He is breeding for size, and wants to have as many watermelons with the phenotype for long shape as possible. In watermelons, the allele for short shape (R) is dominant to the allele for long shape (r). Would crossing a watermelon homozygous recessive for the trait with a watermelon heterozygous for the trait give the most long watermelons possible? Explain your answer using Punnett Squares.
In humans brown eye color is dominant to blue eye color. Suppose that your mother is homozygous and your father is heterozygous and you have brown eyes. If you have a child with blue eyes, what are the possible genotypes of both of your parents? Group of answer choices Mother bb; Father bb Mother BB; Father BB Mother BB or bb; Father Bb Mother Bb ; Father Bb
Fur color in cats is a codominant trait and is located on the X chromosome. Cats can be black, yellow or calico. A calico cat has black and yellow splotches. In order to be calico, the cat must have an allele for the black color and an allele for the yellow color. Use a Punnett square to show why there are no male calico cats.
Thimble foxes cook color is controlled by a single gene while tail length is controlled by a separate Gene. Red coat is dominant to white coat and long tails are dominant to short tails, dominant is complete. Thimble fox one has a red coat and a long tail, its mother had a white coat and short tail. Thimble fox two has a white coat and long tail, its father had a short tail. Complete the punnets square for this cross and give the phenotypic ratio of the offspring. If there is a dominant allele for this first Street, place the gamete in the first give me a position. Then state the Phenotypic ratio.
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
Clouded leopards are a medium sized, endangered species of cat, living in the very wet cloud forests of Central America. Assume that the normal spots (XN) are a dominant, sex-linked trait and that dark spots are the recessive counterpart. Suppose as a Conservation Biologist, you are involved in a clouded leopard breeding program. One year you cross a male with dark spots and a female with normal spots. She has four cubs and, conveniently, two are male and two female. One each of the male and female cubs have normal spots and one each have dark spots. What is the genotype of the mother? Diagram the cross. Suppose a few years later, you cross the female cub that has normal spots with a male that also has normal spots. How many of each genotype will be found in the cubs (assume 4)?
Refer to the figure below, which shows a pedigree of a sex-linked recessive trait. Note that only shaded individuals are affected; unshaded individuals may or may not be carriers. Consider the affected son of female number II-6. If individual III-6 wants to marry and his partner does not carry the allele, the probability that his first son will be affected with the trait is ? percent. 1. 100 2. 50 3. 25 4. 0 5. 75
Complete a Punnett square for a genetic cross of two truebreeding Portuguese water dogs—one with a black, wavy coat (homozygous dominant, BBWW) and one with a brown, curly coat (homozygous recessive, bbww). What is the phenotype ratio of their offspring (F1)? Now ﬁll out another Punnett square, crossing two of the offspring. What is the phenotype ratio of the F2 generation?

Tri-hybrid: Zombie “speed” is a trait determined by the alleles F and f at the speed gene, where fast is dominant to slow. Zombie “brain eating” is a trait determined by the alleles B and b at the brain-eating gene, with eating brains recessive to not eating brains. Zombie drooling is a trait determined by the alleles D and d at the drooling gene where not drooling is recessive to drooling. Cross: A female Zombie that is ffbbDd has offspring with a male Zombie that is FFBbdd. What percentage of the offspring will be fast? What percentage of the offspring will be brain eaters? I'm having trouble with how these is set up as a punnent, and then calculating probability.
The chestnut coat color of horses is due to a recessive gene, while the dominant allele results in black. The pacing gait is due to a recessive gene, whereas the dominant allele results in the trotting gait. Show the types of offspring that could result from a cross of a black trotter (male), heterozygous for both genes, with a chestnut pacer (female).
