7. gene g. specific characteristic
8. multiple alleles h. scientific study of heredity
9. trait i. gene with more than two alleles

completion fill in the blanks:

1. the process in which two genes segregate independently is called

__________.

1. plants that, if left to self - pollinate, produce offspring identical to themselves are called

__________.

1. the offspring of crosses between parents with different traits are called

__________.

1. the process during sexual reproduction in which male and female sex cells join is called

__________.

1. the process of reduction division in which the number of chromosomes per cell is cut in half is called __________.

Explanation:

1. Independent assortment: This is a fundamental principle in genetics where genes for different traits segregate independently during the formation of gametes.
2. True - breeding plants: These plants, when self - pollinated, consistently produce offspring with the same traits as the parent, indicating they are homozygous for the relevant traits.
3. Hybrids: Offspring resulting from crosses between parents with different traits are called hybrids.
4. Fertilization: It is the process in sexual reproduction where male and female gametes (sex cells) fuse together.
5. Meiosis: This is the reduction division process that halves the chromosome number in cells, which is crucial for sexual reproduction to maintain the correct chromosome number in offspring.

Answer:

1. independent assortment
2. true - breeding plants
3. hybrids
4. fertilization
5. meiosis
