57. Genetics Review

58. Practice Question
What inference can be made from the diagram shown?
A. The sperm will have double the amount of chromosomes as the parent cell.
B. None of the cells made copies of their chromosomes
C. The sperm will have half the number of chromosomes as the parent cell.

59. The diagram above shows the process of meiosis
The diagram above shows the process of meiosis. The segregation that occurs during meiosis results in a — A decrease in the total number of cells per organism B reduction in the number of chromosomes per cell C group of genetically identical cells

60. Compare to mitosis, Meiosis will result in
A. 2 Daughter cells B. 4 Daughter Cells C. Less number of daughter cells than mitosis

61. What is the name of this process?
Mitosis
DNA replication
Crossing over

62. Which of the following is NOT a result of Crossing over?
Both chromosomes with identical genes
New combination of genes in each chromosome
Genetic variability

63. Which process of Meiosis is represented by “X”?
Mitosis
Meiosis I
Meiosis II

What is the only genotype of
a yellow pea pod?
Homozygous dominant
Heterozygous
Homozygous recessive C

65. A Pea pod color green (C) is dominant over pea pod color yellow (c).
What is the phenotype of Cc?
Green
Yellow A

66. C Pea pod color green (C) is dominant over pea pod color yellow (c).
Ms. Karle has two pea plants;
One has yellow pods and the other has green pods. What are the genotypes?
CC and Cc
cc and cc
cc and Cc C

67. C Pea plant traits are coded for by genes on chromosomes.
What part of the DNA nucleotide codes for genes thus producing different traits?
Phosphate
Sugar
Nitrogen base C

68. How many PAIRS of autosomes are there?

69. Use the DNA Fingerprint to determine the criminal:
Suspect 2

70. C How do stem cells differentiate into specialized cells?
