Download What is the difference between Autotrophs and heterotrophs?

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.

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

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. Deoxyribose molecule, phosphate group, and nitrogenous base
15. adenine-thymine
cytosine-guanine
