For the three genes shown, identify the row that indicates the alleles that would be found in each of the four gametes produced from this tetrad if a crossover occurred. Select one: a. Gamete 1 Gamete 2 Gamete 3 Gamete 4 AbC AbC aBc aBc b. Gamete 1 Gamete 2 Gamete 3 Gamete 4 Abc AbC aBc aBC c. Gamete 1 Gamete 2 Gamete 3 Gamete 4 Abc Abc aBC aBC d. Gamete 1 Gamete 2 Gamete 3 Gamete 4 Abc ABc abC aBC

Which of the following behaviors of chromosomes explains Mendel's second law (law of independent assortment)?

The rate of crossing over between two linked genes (r and w) is 0.44. The following cross is carried out: Rr Ww × rr ww. What proportion of the gametes of the Rr Ww parent were recombinant gametes? Explain your reasoning and state any assumptions you made.

You are conducting independent research for your Honors Thesis in a Drosophila research lab.  One of the graduate student researchers has provided you with two mutant strains of Drosophila.  One has scarlet eyes, and the other has brown eyes.  You cross homozygous scarlet-eyed male Drosophila with female flies homozygous for the brown-eye color allele, and all of the male and female F1 flies have wild-type eyes.  Crosses involving F1 males x F1 females yield the results shown below. You know the traits involved are autosomal, and that reciprocal parental crosses produce similar results. A) Please define the alleles represented in this cross.  B) List the genotypes of all classes of individuals in the P, F1, and F2Be sure to use the alleles you defined in Part A Parental (P) Generation Genotype of Homozygous scarlet-eyed males: Genotype of Homozygous brown-eyed females: F1 Generation: Genotype of Wild-type (red-eyed) males and females: F2 Generation: Genotype of wild-type males and…

Write the cross using correct symbols. What kind of cross is this called?

I’m having trouble solving this questions about which is best conclusion answer can you please help?

Imagine you are a medical professional, and your patient is pregnant with a child whose karyotype has been determined. The unborn child's karyogram is shown below in the picture.   Create the symbol for this result, and then speculate on the outcome of this pregnancy, based on what you know about the viability of human trisomies.

In the above figure, black and pink lines represent nonhomologous chromosomes. Which of the figures matches the descriptions that follow?
