| Question |
Answer |
| allele | VARIATION OF GENE |
| crossing over | EXCHANGE OF GENETIC MATERIAL BY NON-HOMOLOGOUS CHROMOSOMES DURING PROPHASE I |
| dihybrid cross | FERTILIZATION BETWEEN TWO ORGANIZATIONS TO STUDY TWO DIFFERENT TRAITS. |
| diploid | A CELL WITH TWO COPIES OF EACH TYPE OF CHROMOSOME. |
| dominant | THE OBSERVABLE TRAIT OR THE ONE THAT MASKS THE RECESSIVE. |
| egg | FEMALE GAMETE OR SEX CELL |
| fertilization | FUSION OF MALE AND FEMALE GAMETES. |
| gamete | MALE OR FEMALE SEX CELL |
| genetic recombination | MAJOR SOURCE OF VARIATION IN INDIVIDUALS COMING FROM CROSSING OVER. |
| genetics | STUDY OF HEREDITY |
| genotype | ORGANISM’S GENETIC COMBINATION |
| haploid | CELL OF AN ORGANISM THAT HAS HALF THE NUMBER OF CHROMOSOMES |
| heredity | PASSING ON CHARACTERISTICS FROM PARENTS TO OFFSPING. |
| heterozygous | HAVING NON-IDENTICAL ALLELES FOR A PARTICULAR TRAIT. |
| homologous | PAIRED IDENTICAL CHROMOSOMES |
| homozygous | IDENTICAL ALLELES FOR A PARTICULAR TRAIT |
| Law of Independent Assortment | DIFFERENT TRAITS ARE INHERITED INDEPENDENTLY |
| Law of Segregation | SEPARATION OF ALLELES DURING FERTILIZATION |
| meiosis | CELL DIVISION IN WHICH ONE DIPLOID (2N) CELL PRODUCES 4 HAPLOID CELLS(N) WHICH ARE NOT IDENTICAL TO THE ORIGINAL CELL |
| phenotype | OUTWARD APPEARANCE OF AN ORGANISM |
| pollination | FERTILIZATION BETWEEN MALE AND FEMALE FLOWERS |
| recessive | THE ALLELE THAT IS MASKED BY THE DOMINANT TRAIT |
| sexual reproduction | THE CROSSING OF THE MALE AND FEMALE GAMETES |
| sperm | THE MALE GAMETE |
| trait | A CHARACTERISTIC |
| zygote | THE PRODUCT OR OFFSPRING FROM A FERTILIZATION. |
