Question | Answer |
---|---|
2 sets that have corresponding chromosomes | homozygous |
contains both sets of homologous chromosomes | diploid |
one set of chromosomes | haploid |
chromosomes cut in half in separation | meiosis |
structure with four chromatids | tetrad |
homologous chromosomes that form tetrads | crossing over |
next stage of fertilized egg | zygote |
sperm and egg are also called | gametes |
chromosomes segregate | independently |
True or False The offspring of 2 parents obtains a single copy of every GENE from each parent | true |
True or False A GAMETE must contain one complete set of genes | True |
True or False Genes are located at specific positions on SPINDLES | False/chromosomes |
True or False A pair of corresponding chromosomes is HOMOZYGOUS | False/homologous |
True or False One member of each homologous chromosome pair comes from each GENE | False/Parent |
True or False A cell that contains both sets of homologous chromosomes is HAPLOID | False/ diploid |
True or False The gametes of sexually reproducing organisms are HAPLOID | True |
True or False If an organisms haploid number is 6, it's diploid number is -3- | False/12 |
PHASES Each replicated chromosome pairs with its corresponding homologous chromosome | prophase 1 |
PHASES Crossing over occurs between tetrads | prophase 1 |
PHASES Paired homologous chromosomes line up across the center of the cell | Metaphase 1 |
PHASES Spindle fibers pull each homologous chromosome pair toward an opposite end of the cell | Anaphase 1 |
PHASES A nuclear membrane forms around each cluster of chromosomes and cytokinesis follows, forming two new cells. | Telophase 1 |
PHASES chromosomes consist of two chromatids, but they do not pair to form tetrads | Prophase 2 |
PHASES A nuclear membrane forms around each cluster of chromosomes and cytokinesis follows,forming four new cells | Telophase 2 |
