1. A ..... is the location where genetic information is stored within the nucleus of a cell.
2. A gene that has more than two possible alleles
3. A ..... is a segment of DNA that codes for a particular protein, which leads to a particular trait.
4. Some humans can roll their tongues, while others cannot. Simple dominant traits, such as tongue rolling, are determined in humans by .....
5. Purple flower is dominant to white flower color. Yellow seeds are dominant to green seeds. Two parent pea plants are crossed that are both heterozygous for flower color and seed color. What would be the genotypes for both parents?
6. Mitosis and meiosis both produce new cells through cell division. However, the division process differs due to the kind of cell being produced. How is meiosis different from mitosis?
7. Different variations of a biological inheritance factor
8. If a cross between white flowers (W) and purple flowers (w), which color flower is dominant?
9. What is it called when both alleles are dominant. As a result, the heterozygous phenotype is a combination of each homozygous phenotype.
10. What's a dominant allele?
11. When Mendel crossed purebred pea plants having green pods with purebred plants have yellow pods the offspring were all
12. Which sex chromosomes would indicate a typical human male?
13. In mussels, the allele for brown coloring (B) is dominant, and the allele for blue coloring(b) is recessive. For which parental genotypes are 100% of the offspring expected to be blue?

22. When one allele is dominate and the other is recessive
23. An organism's expressed physical trait, such as color or shape, is called its
24. The observable traits of an organism are known as its
25. A cell with only one set of chromosomes is called ..... and abbreviated as .....
26. If a plant that has round seeds has a parent that has wrinkled seed, what is its genotype? Assume that round is dominant.
27. Pea plants can have green or yellow seeds. In a pea plant that is heterozygous for seed color, the allele for yellow seeds masks the effects of the allele of green seeds. Which of the following terms best describes the allele for yellow seeds?
28. What does phenotype mean?
29. What is called when a organism has two identical alleles for a trait. TT or tt. RR or rr
