You are told that both parent plants in the P generation of the diagram below are homozygous. With this in mind, choose the most likely reason 100% of the F1 generation shows the phenotype for yellow pea seed color.       

Two pea plants (AABB x aabb) were crossed, with the following F2 results:    Non-recombinant 228 AABB Recombinant: 17 AaBb   Recombinant: 26 aaBb Non-recombinant: 60 aabb   From the information provided in the F2 progeny, calculate the recombination frequency (round to next whole %).   

A recessive allele in cats causes orange spots. If two solid-colored cats are mated and produce an orange-spotted kitten, what is the % chance the next kitten would be solid-colored?   

Progeny that exhibit mixing of maternal and paternal alleles on a single chromosome are said to be non-recombinant.   

Given questions #1-10 above, select two statements you identified as “false” and re-write them to make them “true”. As you select a statement to re-write, be sure to write the original question number (Example: “I am re-writing question #7” or simply “#7”). If you do not properly reference your response as instructed, then no points shall be awarded.   When re-writing your false statements, keep each statement to one sentence. You should be able to modify a false statement to make it true by changing just a word or two. Changing a statement to simply include “not” or “don’t” (etc) is not properly re-writing a statement and shall not be accepted. Further, when re-writing your false statements, the modified true statements should pertain directly to course materials, only. Finally, if you re-write more than two statements, only the first two statements will be graded (even if an error is made in re-writing one of the first two statements and a later statement has been re-written properly).  

Penetrance is the percentage of individuals of a given genotype that express the trait coded for by that genotype.   

A cross between two individuals with different phenotypes resulting in ~ 50% of each type of offspring would indicate the cross was ___.   

The following recombination frequencies were found. Determine the order of these genes on the chromosome.   A-B = 40 A-C = 8 C-D = 18 C-B = 32 A-D = 26

Place the following structures in the order of development: morula, blastocyst, zygote, and gastrula.
