A cross is made metween a male AaBbCcDd and a female AaBBccDd
a. How many different germ cells are generated in the male?
b. how many different germ cells are generated in the female?
C Assume that all four genes exhibit complete dominance, how many different phenotypes can be generated in this cross?
Homework Answers
a. types of male germ cells= 24= 16
b. types of female germ cells = 4 ( ABcD, ABcd, aBcD, aBcd)
c.assuming each allele separately,
AaxAa= 2 phenotypes
Bbxbb= 1 phenotype
Ccxcc= 2 phenotypes
DdxDd= 2 phenotypes
multiplying all, 2x1x2x2= 8 phenotypes

A cross was made between a male fruit fly with purple eyes and two different female flies with red eyes. The first female produced 41 progeny that all had red eyes, whereas the second female produced 18 progeny with red eyes and 21 progeny with purple eyes. a. Diagram the two crosses in words (you don't need to show the genotypes yet). b. Which eye color is dominant and which is recessive? How do you know? c. Choose a symbol...

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 certain plant species, inheritance of fruit size is controlled by four genes, each of which has two alleles that show incomplete dominance and each of which contributes equally to an individual’s phenotype. Plants with the largest fruits have the genotype AABBCCDD, while those with the smallest fruits have the genotype aabbccdd. a) How many possible genotypes for fruit size are there in this species? b) Based on genotype alone (ignoring environmental factors), how many possible phenotypes for fruit...

You cross a heterozygous female with a homozygous recessive male for three traits - A B C. You see the offspring ABC 233, abc 239, ABc 231, abC 241, aBc 12, AbC 14, aBC 14, Abc 16. Which of the genes - if any - are linked? How far apart are any/all linked genes? What is the order of genes on the chromosome if applicable?

1. You cross true breeding yellow crossveinless forked (y, cv, and fare autosomal genes) female flies (y-y-cv-cv- f-f- XX) to wild type male flies (y+y+ cv+cV+ f+f+ XY). a. What are the genotype(s) of the F1 progeny? b. How many different combinations of those four traits are possible? c. Assuming simple Mendelian recombination, if we do a test cross with the female F1, what fraction of the F2s will have the phenotype: i. yellow crossveinless forked male? ii. wild type...

You are given a stock of female Drosophila that appears wild type. You cross them with wild-type males and collect progeny, recording the following results: 1,000 wild-type females, 450 wild-type males, and 50 white-eyed males. (Note the male to female ratio.) How many genes are assorting? What phenotypes do they control? Is linkage indicated? If so, what is the map distance?

How to write the Cross for genes that are Linked together? for example a female heterozygous and male that is homozygous recessive. Based on the Chi square I found that there is no independent assortment of genes therefore they are linked. How can I determine correct genotype notation and the cross for linked gene ?

3) Dihybrid cross: The dark-bodied and rudimentary winged genes are on two different autosomal chromosomes. We will use this cross to determine the ratios of phenotypes in the F2 generation when there are two genes involved. 3.1) Use the following symbols to write out the cross: Male: 3 Female: 9 Dark body color (ebony) = e Wild-type body color: E or E+ Rudimentary wings- (vestigial wings= v) Wild-type wings: V or V+ 3.2) What would the cross look like if...
