Dandelions in a lawn that is mowed have short flower stalks, whereas those in a field have tall flower stocks. This illustrates:

A farmer noticed that two of her cotton plants produce cotton with a slight greenish hue. By repeatedly crossing the greenish plants, she has produced a variety of deep-green cotton without the use of any dyes. This is an example of:

Based on your understanding of mitosis, explain the function of this process, where it takes place, and the result of this type of cell division.

What is the ratio of expected phenotypes in the offspring produced by the cross Aa × Aa? Assume complete dominance for the trait. 

If the allele for inflated pea pods (I) is dominant to the allele for constricted pods (i), then the cross Ii x ii is expected to produce: 

All of the following may be found in a DNA nucleotide EXCEPT: 

Patau Syndrome is a chromosomal condition known as Trisomy 13 and is caused by a translocation. Surviving children with this condition have several developmental disabilities, polydactyly, and multiple organ defects among other issues. Explain what Trisomy 13 means, what a translocation is, and when it might occur during meiosis.

The ant Myrmecia pilosula has the smallest number of chromosomes possible in a eukaryote: females possess only one pair of chromosomes, and males have only one chromosome! Put another way, female M. pilosula can be described as having the haploid condition n = 1 and the diploid condition 2n = 2. Based on this scenario as well as your knowledge of gamete formation, a female M. pilosula can produce gametes with ________ different sets of chromosomes. 

Which statement is TRUE of the behavior of chromosomes in mitosis? 

If meiosis did NOT occur in sexually reproducing organisms:
