Traits are are controlled by a single gene, such as corn color, can be used fo predictability of trait in inheritance in humans also. This is especially import for parents who may carry alleles that code for diseases. Parents can predic probabilities that their child might inherit a disease if they know their own genotype. Parents that are carriers (heterozygous) may not show disease, bu can still pass on a disease allele. Read the scenario below (in bold). Using a separate piece of paper and draw out a Punnett square, with required information (questions 1-5). The letter D will be used to represent the domina (healthy) allele. Tom and his wife Julie are both carriers for cystic fibrosis, an autosomal recessive disease. Draw a Punnett square and be sure to include the following information for full credit: 1. Place the parents alleles at the top and on the left side. 2. Write in the allele crosses inside the Punnett squares. 3. Write out the genotypes probabilities for an offspring. 4.…
In humans, the allele for a widow's peak (W) is dominant to the allele for a straight hairline (w). If a person's genotype is Ww, what will their phenotype be? A Homozygous B Heterozygous C Widow’s peak D Straight hairline Answer is C. Widow's peak? Can you help me to explain to me step by step
In cats, a temperature-sensitive allele produces the Siamese phenotype, in which the cooler extremities are dark and the warmertrunk area is lighter. A Siamese cat that spends most of its timeoutside was accidentally injured in a trap and required severalstitches in its right front paw. The veterinarian had to shave the furfrom the paw and leg, which originally had rather dark fur. Later,when the fur grew back, it was much lighter than the fur on theother three legs. Do you think this injury occurred in the hot summer or cold winter? Explain your answer

Pedigree Charts A pedigree for any family, be it dogs, cats or humans, shows the pattern of inheritance in a family for a specific trait. Males are shown as squares and females are shown as circles. Each generation is shown as a Roman numeral and each person in a generation is numbered. The trait that is being expressed is shown as a shaded shape. Observe the pedigree. Number the generations and each person on the pedigree. In this family, how many individuals show the trait? Which males show the trait? (generation,number) Determining genotypes Follow along in the presentation so you can figure this out. N = normal feet, n = webbed feet. Write down the genotypes of each individual under him/her. Can you determine the genotype of individual IV,2? Explain why or why not
Lamarck is remembered for his theory of inheritance which hypothesized that physical characteristics acquired during an individuals lifetime were passed onto their offspring (long neck in giraffes). How does this differ from epigenetic inheritance where the diet of the agouti/diabetic mother affects coat color and body size of the offspring (born brown and slim)? O The change in coat color occurs in the offspring and not in the mother O Diet has no impact on fur color, but it can effect body size O There is no difference between Lamarckian theories of inhertiance and epigenetic inheritance O Many genes are involved in determining fur color and body size, making it unlikely that DNA methylation can cause a persistent change in fur color and body size
Which of the following statements describes the multifactorial inheritance in genetics? O Phenotype is determined by different environmental factors. O One locus is associated with variable phenotypes of a trait. Several loci are associated with the trait. One locus is associated with different traits. O Environment plays minimal or no role in the final phenotype.
A geneticist from an alien planet that prohibits genetic researchbrought with him to Earth two pure-breeding lines of frogs. Oneline croaks by uttering “rib-it rib-it” and has purple eyes. The otherline croaks more softly by muttering “knee-deep knee-deep” andhas green eyes. With a newfound freedom of inquiry, the geneticistmated the two types of frogs, producing F1 frogs that were allutterers and had blue eyes. A large F2 generation then yielded thefollowing ratios:27/64 blue-eyed, “rib-it” utterer12/64 green-eyed, “rib-it” utterer9/64 blue-eyed, “knee-deep” mutterer9/64 purple-eyed, “rib-it” utterer4/64 green-eyed, “knee-deep” mutterer3/64 purple-eyed, “knee-deep” mutterer(a) How many total gene pairs are involved in the inheritance ofboth traits? Support your answer.(b) Of these, how many are controlling eye color? How can youtell? How many are controlling croaking?(c) Assign gene symbols for all phenotypes and indicate thegenotypes of the P1 and F1 frogs.(d) Indicate the genotypes…
In humans, a dimple in the chin is a dominant characteristic controlled by a single gene.a. A man who does not have a chin dimple haschildren with a woman with a chin dimple whose mother lacked the dimple. What proportion of theirchildren would be expected to have a chin dimple?b. A man with a chin dimple and a woman who lacksthe dimple produce a child who lacks a dimple.What is the man’s genotype?c. A man with a chin dimple and a nondimpledwoman produce eight children, all having the chindimple. Can you be certain of the man’s genotype?Why or why not? What genotype is more likely,and why?

. Tay-Sachs disease is a rare human disease in which toxic substances accumulate in nerve cells. The recessiveallele responsible for the disease is inherited in a simpleMendelian manner. For unknown reasons, the allele ismore common in populations of Ashkenazi Jews ofeastern Europe. A woman is planning to marry her firstcousin, but the couple discovers that their sharedgrandfather’s sister died in infancy of Tay-Sachsdisease.a. Draw the relevant parts of the pedigree, and showall the genotypes as completely as possible.b. What is the probability that the cousins’ first childwill have Tay-Sachs disease, assuming that all peoplewho marry into the family are homozygous normal?
A family from coastal Africa recently moved to Canada. Soon after the move, their 6-month-old baby starts napping more frequently and often cries as if in pain. Concerned, the parents take their baby to a pediatrician, who diagnoses the baby with Sickle Cell Disease. The parents are astonished; neither has Sickle Cell Disease nor do their parents or siblings. How could this be possible? Use your knowledge of Mendelian Genetics and patterns of Inheritance to explain how this baby has Sickle Cell Disease when neither parent exhibits this disease phenotype. What term(s) could be used to describe the genotype of the baby's parents? What term(s) could be used to describe the genotype of the baby with Sickle Cell Disease?
