A Chromosome Study Lab An examination of the chromosomes of a cell under high magnification can give much information about an organism. Figure 1 shows the chromosomes of a somatic cell as they might appear in an organism if enlarged many times their natural size. A somatic cell is any cell making up the organism except for reproductive cells. In this investigation‚ it is expected that you: a. learn what a chromosome Karyotype is. b. prepare a Karyotype of chromosomes according to the instructions

3. In some pea plant crosses‚ the plants are self-pollinated. Refer back to Concept 13.1 (pp. 248–249) and explain whether self-pollination is considered asexual or sexual reproduction. 3. Self-pollination is sexual reproduction because meiosis is involved in forming gametes‚ which unite during fertilization. As a result‚ the offspring in self-pollination are genetically different from the parent. (As mentioned in the footnote on p. 263‚ we have simplified the explanation in referring

Anatomy of the Male Reproductive System Scrotum The scrotum is a sac-like organ made of skin and muscles that houses the testes. It is located inferior to the penis in the pubic region. The scrotum is made up of 2 side-by-side pouches with a testis located in each pouch. The smooth muscles that make up the scrotum allow it to regulate the distance between the testes and the rest of the body. When the testes become too warm to support spermatogenesis‚ the scrotum relaxes to move the testes away

Biology Exam 2013 - Review UNIT: PATERNS OF INHERITENCE Describe Mendel’s experiments: * Chose a female parent; chooses a male parent; pollen is collected from the stamens and dusted onto the female parent stigma; pollen fertilizes the eggs. The ovary develops into the pod and eggs develop into the peas; when peas are planted they develop into pea plants. Why Pea Plants? * Easily obtained * Grown quickly; several generation of peas can be observed * Traits are easily visible
