You decide to breed a pair of guinea pigs, one black and one white. In guinea pigs, black fur is caused by a dominant allele (B) and white is due to homozygosity for a recessive allele (b) at the same locus. Your guinea pigs have seven offspring, four black and three white. What are the genotypes of the parents? Why is there a 1:1 ratio in this cross?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
When you decide to breed your Labrador retriever Molly and sell the puppies, you discover that two of Mollys four siblings have developed a hip disorder that is traceable to the action of a single recessive allele. Molly herself shows no sign of the disorder. If you breed Molly to a male Labrador that does not carry the recessive allele, can you assure a purchaser that the puppies will also be free of the condition? Explain your answer.
Hemophilia and color blindness are both recessive conditions caused by genes on the X chromosome. To calculate the recombination frequency between the two genes, you draw a large number of pedigrees that include grandfathers with both hemophilia and color blindness, their daughters (who presumably have one chromosome with two normal alleles and one chromosome with two mutant alleles), and the daughters sons. Analyzing all the pedigrees together shows that 25 grandsons have both color blindness and hemophilia, 24 have neither of the traits, 1 has color blindness only, and 1 has hemophilia only. How many centimorgans (map units) separate the hemophilia locus from the locus for color blindness?
As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progeny
The text outlines some of the problems Frederick William I encountered in his attempt to breed tall Potsdam Guards. a. Why were the results he obtained so different from those obtained by Mendel with short and tall pea plants? b. Why were most of the children shorter than their tall parents?
In guinea pigs, black hair is dominant over white hair. If a homozygous black guinea pig (father) were crossed with a homozygous white guinea pig (mother), the first generation of offspring would be all black.Match the mother's and father's genotypes and phenotypes to their correct description. 1. mother's phenotype 2. father's phenotype 3. father's genotype 4. mother's genotype a. black b. HH c. white d. hh
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.
The allele for hitchhiker’s thumb (h) is recessive to straight thumb (H). If a man and his wife are both homozygous recessive, will any of their offspring potentially have hitchhikers thumb? What is the man’s genotype and the woman’s genotype? What is the man’s phenotype and the woman’s phenotype? What genotype(s) must the offspring have in order to have the phenotypic trait of hitchhiker’s thumb? Do a cross to determine all potential hitchhiker’s thumb genotypes and phenotypes for the offspring of this man and woman. Is it possible for any offspring of the F1 generation to have hitchhiker’s thumb?
In a certain plant, the orange flower allele (Y) is dominant to the yellow flower allele (y). An allele that prevents flower color pigment formation (W) results in white flowers irrespectively of the Y and y alleles, and is dominant to an allele (w) that allows flower color formation. What is the expected proportion of phenotypes in the offspring of a cross between two dihybrid white-flower plants? 1/3 white flowers, 1/3 orange flowers, 1/3 yellow flowers 9/16 white flowers, 3/16 orange flowers, 3/16 yellow flowers, 1/16 orange-yellowish flowers 12/16 white flowers, 3/16 orange flowers, 1/16 yellow flowers 6/8 white flowers, 1/8 orange flowers, 1/8 yellow flowers 1/2 white flowers, 1/4 orange flowers, 1/4 yellow flowers
In rabbits, black fur (F) is dominant to white fur (f). You decide to cross a rabbit that is homozygous dominant for fur color with a rabbit that is heterozygous for fur color. Set up a Punnett Square for this cross and then answer the following questions. What percentage of offspring will have the FF phenotype?What percentage of offspring will have the ff phenotype?What percentage of offspring will have the Ff phenotype?
In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
