You cross the following individuals A/a;B/B;X/X X a/a;b/b;XC/ What proportion of the offspring will be a...
You cross the following individuals A/a;B/B;XC/Xc X a/a;b/b;XC/Y What proportion of the offspring will be a male showing all dominant phenotypes? Please show your work.
4. You cross individuals with the following Genotypes, AaBbDdEeFFGg & AaBbDDEeFfGg. Predict the proportion of offspring that would show the following Phenotype or Genotype? A) all Dominant Phenotypes, B) the Genotype: AabbDdEeFfgg, C) the Genotype: AABbDdEeFfgg, D) the Genotype: aaBbddEeffGg, & E) all Recessive Phenotypes. 5. You cross individuals with the following Genotypes, AaBbDdEeFFgg x AabbDDEeFfGg. If you produce 1000 offspring in this cross, predict the number of offspring that would have the following Phenotype or Genotype? A) all Dominant...
Given the following genotypes: QqRRSs x QqrrSs, what is the probability of producing offspring that present only one dominant feature? Show your work. For a sex-linked disorder such as hemophilia, illustrate the punnett square and pedigree for the offspring of an affected male (X Y) and carrier female (X^AX^a). Show your work. What is the probability of having an affected daughter? What is the probability of having a normal male?
17. In a simple monohybrid cross the individuals of 100% known genotype in the F2 offspring, are which of these? a) the heterozygous individuals b) the homozygous dominant individuals c) the homozygous recessive individuals d) you could not determine the geneotype of any offspring without performing additional tests. 18. If an individual contains two alleles for a particular gene and the two alleles are different from each other, the individual is said to be: a) homozygous dominant b) homozygous recessive...
(6) Given each of the following crosses, determine the expected proportion of offspring with the given phenotype. Assume independent assortment. You must show your work or explain your reasoning to receive credit. Note: embryos that do not survive to be born are not considered "offspring." a. Cross: Il BB dd Cc w w mm x Il BB Dd Cc w w mm What proportion of offspring is expected to be albino? What proportion of offspring is expected to be gray?...
In a trihybrid cross between individuals who are heterozygous for all three traits, the expected proportion of offspring showing dominance for one trait and recessive for the other two is 1/16 1/64 27/64 9/16 9/64
Observing the phenotypic ratio of the offspring generation of a mated pair can increase our understanding of inheritance of traits. In wolves, gray fur and yellow eyes are dominant, black fur and blue eyes are recessive, and both traits are governed by simple (complete) dominance In the Ely, MN area there exists an alpha pair: a male dihybrid (double heterozygote) wolf displaying both dominant phenotypes mated with a female wolf recessive for both traits. Researchers hypothesize the two genes (fur...
BIO 142 Test X 9) Curly hair (CC) is incompletely dominant over straight hair (ce), therefore the heterozygous genotype (Ce) produces wavy hair (Ce), Set up the Punnet square and cross a mother with wavy hair with a man with wavy hair. (5 points) What is the percentage of different phenotypes of their children? Show your works. Female Genotype: Genotype ratio Phenotype ratio: Male Genotype: 10) Cross a father with blood type AO and a mother with BO blood type....
4. Now, assume that a F1 male and a F1 female offspring produced by the cross in #3 above mate with each other. F1 offspring : XXGgBb and XYGgBb Note: You can ignore the X and Y chromosomes here in question 4. Why? The traits of interest (fire-breathing and laser-shooting) are autosomal, so the sex of the fly (XX=female or XY=male) will not impact the trait expressed. You only need to follow the inheritance of chromosomes 2 and 3 for...
In a cross between two mottled offspring, what is the probability of getting a mottled offspring? (2 points) In a cross between two mottled flowers, if there are two offspring, what is the probability of getting one black offspring and one white offspring? (2 points) In a cross between two mottled flowers, if there are two offspring, what is the probability of getting one white offspring and one mottled offspring? (2 points) In a cross between mottled flowers, if there...
