genetics 1. Normal cell has 2N number of chromosomes and a gamete has a haploid number; egg is larger 2. meiosis 3. Diagram showing gene combinations that might result from a genetic cross 4. genes- chemical factors that determine traits allele- different forms of a gene 5. homozygous- two identical alleles for a particular trait (T,T) heterozygous- two different alleles for the same trait (T,t) 6. P is parent, F1 is first generation, F2 is second generation 7. The dominant traits covers/masks the recessive trait. 8. 9. a. TT x tt b. Tt x tt c. Tt x Tt a. separation of alleles during gamete formation b. independent segregation of genes during the formation of gametes c. result of the cytoplasm not dividing evenly d. chromosome that is not a sex chromosome e. two different alleles for the same trait f. two identical alleles for a particular trait g. gene located on the X or Y chromosome 10. Male= XY Female= XX 11. 1 12. Crossing over- process in which homologous chromosomes exchange portions of their chromatids during meiosis translocation- part of one chromosome breaks off and attaches to another nondisjunction- error in meiosis in which homologous chromosomes fail to separate 13. replication- copying process where cell duplicates its DNA transcription- process in which part of the nucleotide sequence of DNA is copied into a complementary sequence in RNA translation- decoding of mRNA message into a polypeptide chain 14.
