Question 1: How many sets of genes are found in most adult organisms?

Answer:

The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and two complete sets of genes.

Question 2: What events occur during each phase of meiosis?

(Prophase I)

Answer:

In prophase I of meiosis, each replicated chromosome pairs with its corresponding homologous.

Question 3: How is meiosis different from mitosis? (Part II)

Answer:

Mitosis does not normally change the chromosome number of the original cell. This is not the case of meiosis, which reduces the chromosome number by half.

Question 4: How can two alleles from different genes be inherited together?

Answer:

Alleles of different genes tend to be inherited together from one generation to the next when those genes are located on the came chromosome.

Question 5: Fertilization

Answer:

Process in Sexual Reproduction in which male and female reproductive cells join to form a new cell.

Question 6: Haploid

Answer:

Term used to refer to a cell that contains only a single set of genes.

Question 7: Gamete

Answer:

Sex cell.

Question 8: Independent Assortment

Answer:

One of Mendel's principles that states that genes for different traits can segregate independently during the formation of gametes.

Question 9: Incomplete Dominance

Answer:

Situation in which one allele is not completely dominate over another allele.

Question 10: Co-Dominance

Answer:

Situation in which the phenotypes produce by both alleles are completely expressed.

Question 11: Hybrid

Answer:

Offspring of crosses between parents with different traits.

Question 12: How do alleles segregate when more than one gene is involved?

Answer:

The principle of independent assortment states that genes for different traits can segregate independently during the formation of gametes.

Question 13: How is meiosis different from mitosis? (Part III)

Answer:

Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells.

Question 14: Allele

Answer:

One of a number of different forms of a gene.

Question 15: Diploid

Answer:

Term used to refer to a cell that contains two sets of homologous chromosomes.

Question 16: Does the environment have a role in how genes determine traits?

Answer:

Environmental conditions can affect gene expression and influence genetically determined traits.

Question 17: What events occur during each phase of meiosis?

(Anaphase I)

Answer:

During Anaphase I, spindle fibers pull each homologous chromosome pair toward opposite ends of the cell.

Question 18: Probability

Answer:

likelihood that a particular event will occur.

Question 19: What are some exceptions to Mendel's principles?

Answer:

Some alleles are neither dominant nor recessive.

Question 20: What are some exceptions to Mendel's principles? (Part 2)

Answer:

Many genes exist in several different forms and are therefore said to have multiple alleles.

Question 21: What are some exceptions to Mendel's principles? (Part 3)

Answer:

Many traits are produced by the interactions of several genes.

Question 22: Heterozygous

Answer:

Having two different alleles for a particular gene.

Question 23: What did Mendel contribute to our understanding of genetics?

Answer:

Mendel's principles of heredity, observed through patterns of inheritance, form the basis of modern genetics.

Question 24: Meiosis

Answer:

Process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.

Question 25: Crossing-over

Answer:

Process in which homologous chromosomes exchange portions of their chromatids during meiosis.

Question 26: How is meiosis different from mitosis?

Answer:

In mitosis, when the two sets of genetic material separate, each daughter cell receives one complete set of chromosomes. In meiosis, homologous chromosomes line up and then move to separate daughter cells.

Question 27: What events occur during each phase of meiosis? (Metaphase I)

Answer:

During metaphase I f meiosis, paired homologous chromosomes line up across the center of the cell.

Question 28: Zygote

Answer:

A fertilized egg.
