zygote also went through mitosis to develop the sporophyte. Mitosis is the process that creates haploid gametes‚ because it ensures the haploid gametes do not loose half of its chromosomes and cell data‚ which would be the result if it underwent meiosis (Hoefnagels.

Disjunction is the failure of chromosomes to separate properly. Non disjunction may occur during anaphase 1 or anaphase ii. If the tetrads do not separate normally during anaphase 1‚ an entire tetrad can end up on one side‚ therefore during the stages of meiosis ii gamates can be produced that either have extra chromosomes or are missing chromosomes. In the case of Down Syndrome the non disjunction has produced a gamete with an extra chromosome 21. 24a) Interphase 1 – there are three double stranded

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

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
