Question-1: answer:
Answer: Given the genotypes as: QqRRSs x QqrrSs; what is the probability of producing offspring that present only one dominant feature?
Trihybrid cross: probability of offspring dominant one production from cross between QqRRSs x QqrrSs
Qq x Qq ------------> QQ Qq Qq qq -----------> dominant one probability is about 1/2
RR X rr --------------> Rr Rr Rr Rr ----------------> dominant one prbability is about 1/2
Ss x Ss -------------> SS Ss Ss ss --------------> dominant one probability is about 1/2
Total dominant probability ------> 1/2 x 1/2 x 1/2 ----> 1/8
Given the following genotypes: QqRRSs x QqrrSs, what is the probability of producing offspring that present...
Hemophilia Procedure: Create a Punnett square that determines the probability of male offspring having hemophilia when the father has hemophilia (Y Xh) and the mother is a carrier (XH Xh). Record the results. What were the possible genotypes of the offspring? Out of only the male offspring, what is the probability (percentage) of a male being afflicted with hemophilia of only the male offspring? How many females (what number of females) would be expected to have hemophilia out of the...
1. For each of the following blood types, list the possible genotypes: Phenotype Possible Genotypes A B AB O 2. Dr. Paul is blood type O. His father was blood type A and his mother was blood type B. What were the genotypes of his parents? What are the possible blood types and phenotypic ratios expected for a cross involving these parental genotypes? 3. In the ABO blood system in human beings, alleles A and B are codominant and both are...
SEX-LINKED TRAITS 8. Create a Punnett square to determine the offspring that would result from a cross between a woman with normal vision, who carries the allele for color-blindness, and a man who has normal vision. Note: color-blindness is an X-linked recessive tret What are the genotypes of the parent? List all possible genotypes of the offspring. male, normal male, color-blind female, normal vision female, carrier 50% Co hat percentage of their sons would be color-blind? What percentage of their...
d. What percent of the offspring will be carriers of the white yel! 2. Using the same information as for question #1, cross a heterozygous red-eyed female with a red-eyed male. 1. What are the genotypes of each parent? b. What fraction of the children will have red eyes? c. What fraction of the children will have white eyes? d. What fraction of the female children will carry the white eyed trait? 3. In humans, hemophilia is a sex-linked recessive...
7. If offspring exhibit a 3:1 phenotypic are the parents' genotypes? f purple flower color in a plant is controlled by the allele Rand white flower.com by the allele, which flower color is dominant? and white flower color is controlled 9. If a heterozygous purple flowered plant is crossed with a white flowered plant w phenotypes of their offspring? as 10. If the offspring of a cross are 50 purple-flowered plants and 14 white-flowered plants, what are the genotypes of...
all XY male offspring will be affected
all female offspring will be affected
half of the offspring will be affected regardless of their
sex
1/4 of the offspring will be affected regardless of their
sex
half of XY male and 1/4 of XX female offspring will be
affected
X-inactivation happens randomly in development of XX humans. If it occurred at the one-cell stage (immediately after fertilization before any cell divisions occur in the embryo), What would be the best prediction...
that's all the professor give
3. In pigs, black hair (B) is dominant to red hair (b). Erect ears (E) are dominant to drooping ears (e). What are the expected proportions of the different phenotypes resulting from a mating between two pigs heterozygous for both traits? SHOW A PUNNETT SQUARE 4. There are 2 colors in color squash, white & yellow. White (W) is dominant over yellow (w). What are the expected genotype and phenotype frequencies for each of the...
Hemophilia is a sex-linked recessive trait. If a hemophiliac male marries a carrier female, what percent of their daughters will have hemophilia? The gene for yellow body color in Drosophila is recessive and sex-linked. Its dominant allele b+ produces wild-type body color while the recessive allele, b- produces yellow body color in homozygous individuals. List the phenotypes and genotypes of the progeny from the following matings: a. yellow female x wild-type male b. wild-type (carrier) female x wild-type male c....
I did 1-5 but confused on the rest
LAB EXERCISE 4.1 continued Name 6 Remember that the ability to taste PTC is dominant to the inability. Two normally pigmented taster parents have an albino, taster son and a non-taster daughter with normal pigmentation. Using A and Tand a and t for the dominant and recessive alleles, respectively, create a Punnett square for two traits, as shown on pages 71-73 in the section "Transmission of Autosomal Traits: Two at a Time."...
need help with 1 and 2 please.
X-linked Recessive Traits Review X-linked traits in your textbook. 1 In cars, the Ballele produces black fur & b produces orange fur. This gene is X-linked (X & X". Both colors are expressed in heterozygotes calico). If alcat has 2 calico kittens, 1 male black kitten, and I female orange kitten, what is the ty p henotype of the father cat? (Hint: Work backwards & use a Punnett square Remember that not every...
