Four pea-plant crosses, each worked to a ratio and followed by the meiotic event behind it, fill the finished inheritance problem set shown for Week 6 of INHE 1001. Searches like "inhe 1001 week 6 assignment example", "inhe1001 week 6 sample" and "inhe 1001 week 6 example" land here.
What a finished INHE 1001 Week 6 inheritance problem set looks like
Each problem is laid out identically. A key defines the allele symbols and which is dominant. The parental genotypes appear next, then the gametes each parent can produce, then the Punnett square, then the offspring ratios by genotype and by appearance. What sets the example apart is the line following each answer. After the single-trait cross, that line says the three-to-one ratio appears because the two alleles of a parent separate into different gametes when homologous chromosomes part in meiosis. After the test cross, it says how the offspring reveal a hidden genotype. After the two-trait cross, it ties the nine-three-three-one pattern to chromosome pairs lining up independently of each other. The final problem gives offspring counts that miss that pattern, and the line names linkage as the likely cause.
How a INHE 1001 Week 6 example is structured
Problems increase in difficulty and each one reuses the machinery of the one before, so the set reads as a single argument built in stages. Notation is fixed in a key at the top and never changes, which removes the most common source of arithmetic errors. Within each problem the working is visible: gametes listed before the square, the square before the ratio. The explanation line sits directly under the ratio instead of in a separate section at the end, because a ratio and its mechanism belong together. Gregor Mendel is credited for the principles of segregation and independent assortment, at the problems that display them. The last problem is deliberately different in kind, asking what an unexpected result reveals, and it carries the set's longest explanation.
A key before any square
Allele symbols and dominance are defined once at the top. Sets introducing notation mid-problem, or changing case conventions between problems, lose accuracy credit even when the ratios come out right.
Gametes listed first
Each parent's possible gametes appear before the square is filled. That line is where segregation actually happens on the page, and skipping it hides the step the explanation later depends on.
Ratio, then reason
Under every ratio sits one sentence naming the meiotic event behind it. The ratio alone shows the author can count; the sentence shows the author knows why the count comes out that way.
The test cross as detective work
The example explains how crossing an unknown plant with a recessive one exposes its genotype. That problem is the clearest demonstration that ratios are evidence about genes, not merely results.
When the numbers miss
Counts departing from the expected dihybrid pattern are read as information. Linkage, two genes sitting close on one chromosome, is proposed as the mechanism, which is the set's step past arithmetic.
Where marks go in INHE 1001 Week 6
Correct squares are expected and carry less weight than the time spent on them suggests. Points concentrate in the interpretation lines, where a ratio has to be tied to segregation or independent assortment by naming what chromosomes do in meiosis. A set filling every square perfectly and never saying why a ratio appears sits in the middle band. Notation errors cost next: a switched symbol partway through a problem produces a wrong answer that no explanation can rescue. Probability language is read carefully, and a claim that a quarter of the offspring will certainly show the recessive trait draws a comment, since ratios describe expectation across many offspring. The final problem is where strong sets separate from adequate ones, by treating an unexpected count as evidence rather than as a mistake.

Problem sets vary by textbook, so the actual problems your classroom assigned should travel with the prompt and rubric. Custom worked solutions follow, each ratio explained by its mechanism, back in 24-48h and free for a first set. Bare answers would not match what is graded here, which is why every problem arrives with its reasoning visible.
INHE 1001 Week 6 questions, answered
Why explain a ratio that the square already shows?
Because the square shows the result and the course grades the cause. A Punnett square is a bookkeeping device; it produces three-to-one without saying why alleles separate. The explanation line connects that bookkeeping to chromosomes separating during meiosis, which is the biology the problem set exists to test. Without it, the set demonstrates arithmetic that a spreadsheet could perform just as well.
What if my section uses fruit flies or another organism?
The organism changes and the reasoning does not. Fruit fly problems often add sex-linked traits, which need one more explanation: why a trait carried on the X chromosome appears in different ratios in males and females. The example's structure, key, gametes, square, ratio and reason, carries over directly, and the extra line simply names the chromosome the gene sits on.
How much probability math is expected?
Enough to express ratios as fractions and to combine independent events by multiplying, which is how a two-trait probability is calculated from two single-trait ones. The example shows that multiplication once, beside the dihybrid square, as a check on the counting. More advanced statistics, such as testing whether observed counts fit expectation, appear only when a prompt calls for them.
