Question

7 multiple choice 10 points a cells complete complement of dna is known as the rna dna polymerase genome chromatin 8 multiple answer 10 points which of the following is true about the event called \crossing - over\? (choose all answers that are true.) crossing - over occurs in prophase ii of meiosis crossing - over creates recombinant chromosomes crossing - over increases the variation in a species crossing - over creates extra chromosomes during meiosis 9 multiple choice 10 points a recessive trait will be observed in individuals that are for that trait. homozygous dominant homozygous recessive heterozygous

Explanation:

• For question 7, a cell's complete DNA complement is the genome. RNA is a different nucleic - acid, DNA polymerase is an enzyme for DNA replication, and chromatin is the DNA - protein complex.
• For question 8, crossing - over occurs in prophase I of meiosis, creates recombinant chromosomes, and increases genetic variation in a species. It does not create extra chromosomes.
• For question 9, a recessive trait is observed in homozygous recessive individuals. Homozygous dominant shows the dominant trait, and heterozygous shows the dominant trait as well.

Answer:

1. C. genome
2. B. Crossing - over creates recombinant chromosomes, C. Crossing - over increases the variation in a species
3. B. homozygous recessive
