When Mendel crossed purebred purple-flowered plants with purebred white-flowered plants, the resultant offspring were all purple-flowered. This F1 generation produced white-flowered plants as well as p pt 1 when allowed to self-pollinate.
The Punnet square in figure 7.1 represents a cross between two parents with the genotype Ss for a recessive allele-related genetic disorder. Any of the following individuals will be affected by the genetic disorder? offspring of ss
What is the key distinction between a sex-linked disease carrier and an autosomal disorder carrier? A sex-linked disorder’s carrier is always female, but she does not have the disorder.

The DNA molecule is packaged into thread-like structures called chromosomes in the nucleus of each cell. DNA is tightly coiled several times around proteins called histones that maintain the structure of each chromosome.
When a cell is not dividing, chromosomes are not detectable in the nucleus, even under a microscope. During cell division, however, the DNA that makes up chromosomes becomes more tightly packed and visible under a microscope. The bulk of what scientists know about chromosomes comes from studying them during cell division.
The centromere, a constriction point on each chromosome, divides the chromosome into two parts, or “arms.” The “p arm” refers to the chromosome’s short arm. The “q arm” refers to the chromosome’s long arm. The centromere’s position on each chromosome determines the chromosome’s form and can be used to identify the location of specific genes.
