Explain how to arrive at the estimate that one human couple can produce over 70 trillion unique offspring.

Let's go back to the image from the "Think About It." Use your new vocabulary, evidence from the lessons, and scientific reasoning to support the claim, "While there are many types of asexual reproduction, all types result in offspring identical to each other and the original parent." You may include a model or sketch as support for the claim. Submit your optional hand-drawn or digital model or sketch in the file upload question. B I iii !!! (a) (b) (C) (d) (e)

in a randomly mating laboratory population of Drosophila, 4% of the flies have black bodies, and 96% have brown bodies. Flies with brown bodies always have at least one parent with a brown body. What is the frequency of heterozygotes in this population?     0.04     0.16     0.08     0.32   The period gene of Drosophila melanogaster encodes for a stretch of Thr-Gly repeated in tandem. In natural populations, the three most common alleles encode for 17, 20 and 23 Thr-Gly repeats.  The amplification by PCR of the allele encoding for 20 Thr-Gly repeats produces a fragment of 320 bp. Using the same set of primers, what is the size expected when amplifying the 17 Thr-Gly allele?     317     303     314     302       in a certain species of plant loci A, B and C have an additive effect on the colour of the flower. Alleles A, B, and C are dominant and alleles a, b and c are recessive.  Knowing that a plant with genotype AAbbCc has a…
