1. Alleles are different versions of the same gene and one may be dominant to the other. –TRUE 2. In a dihybrid cross of a mother and father who are both heterozygous dominant for chin fissures and dimples‚ what would be the phenotypic ratio of chin fissures and dimples in their offspring? –-9:3:3:1 3. If two alleles are heterozygous‚ it means they are the same allele. --FALSE 4. If the letter ""C"" stands for the dominant allele for having a chin fissue and the letter ""c"" stands for the recessive

1. Simulate Mendel’s experiments using a dihybrid cross‚ in which he defined the law of independent assortment. Use two physical traits in dragons – Color and body covering. The color locus has two alleles: Green (G) which is dominant‚ and yellow (g) which is recessive. The skin locus also has two alleles: Scaled (S) is dominant to scaleless (s). a. What types of dragons would you use as the parental generation? b. What would be the phenotype(s) of the F1 generation dragons? c. Write

expression of another (as in the baldness/widow ’s peak mentioned earlier). Bateson reported a different phenotypic ratio in sweet pea than could be explained by simple Mendelian inheritance. This ratio is 9:7 instead of the 9:3:3:1 one would expect of a dihybrid cross between heterozygotes. Of the two genes (C and P)‚ when either is homozygous recessive (cc or pp) that gene is epistatic to (or hides) the other. To get purple flowers one must have both C and P alleles present. Explanation: In genetics‚ epistasis is

It also shows how genes can sometimes make certain organisms look odd‚ like my dragon with his long neck and short tail. Nonetheless‚ I am very proud of my dragon‚ Norbert II. The second item on the right side of my journal I would consider my best work is the Bikini Dihybrid cross on page 88. This is because

Tables 3-4A and 4-4B 3-4A) For this collected set of data‚ our mission was to test mendilan null hypothesis which stated that the ratio of a dihybrid( Ear#2) would result in a 9:3:3:1 ratio. The result for out p-value was between .70-.50 which was greater than .05. The value of the chi-square was between the approved range for the hypothesis to be accepted‚ therefore‚ the null hypothesis was accepted

Does the genes from both parent combine into 1 or are the inherited by a whole where 1 is express while the other stays dormant. Using Mendel’s Laws as a base for our experiment‚ we will determine the expected outcome of these

gametes during meiosis in the F generation. The F can be thought of as having been formed 1 1 from two haploid “input” gametes. In this case‚ the F is a dihybrid with AB on one chromosome and ab on the other 1 chromosome. You can tell this by looking at the parents. The F1 hybrid got AB from one parent and ab from the other parent (AB/ab). A dihybrid that is AB/ab can produce four possible “output” gametes through meiosis. Output gametes that match one of the input gametes are nonrecombinant (AB or
