99 27. In what stage can crossing over take place? PROPHASE 1

100 An organism has 18 chromosomes in an unfertilized egg. 28.How many pairs of chromosomes are there? 0- only one of each type of chromosome

101 An organism has 18 chromosomes in a fertilized egg. 29. How many pairs of chromosomes are there? 9 pairs of homologous chromosomes that total up to 18 total chromosomes. Another name for a fertilized egg is a zygote.

102 An organism has 18 chromosomes in a body cell. 30. How many pairs of chromosomes are there? 9 pairs of homologous chromosomes that total up to 18 total chromosomes

103 Review Questions 1. If there are 7 chromosomes in a cell. Is it a gamete or a somatic cell?

104 2. If there are 14 chromosomes in a cell. Is it a gamete or a somatic cell?

105 3. Define fertilization.

106 4. How many pairs of chromsomes are in a zygote (fertilized human egg)?

107 5. How many pairs of chromsomes are in an unfertilized egg?

108 6. How does meiosis differ in males and females?

109 Review Questions ANSWERS 1.If there are 7 chromosomes in a cell. Is it a gamete or a somatic cell? GAMETE- Somatic Cells have pairs of chromosomes so can’t be a somatic cell because the number of chromosomes is odd

110 2.If there are 14 chromosomes in a cell. Is it a gamete or a somatic cell? Can’t tell. Need more information. If it is a gamete, there would be 28 chromosomes in the zygote (fertilized egg) and body cells. If it is a somatic cell, there would be 14 chromosomes in cell (and 7 in the gamete).

111 3.Define fertilization. Sperm + egg restoring the diploid number.

112 4.How many pairs of chromsomes are in a zygote (fertilized human egg)? 23 pairs

113 5.How many pairs of chromsomes are in an unfertilized egg? 0 pairs- 23 single chromosomes (one of each homologous pair)

114 6.How does meiosis differ in males and females? Females- Oogenesis- 1 of 4 is viable egg. Less eggs produced in life than sperm. Males- Spermatogenesis- all 4 are viable sperm. More sperm produced in life than eggs.
