DNA Replication Flashcards
Somatic cells
Body cells
Are diploid
Diploid Cells
2 full sets of chromosomes
)
Gametes
Sex cells
Are haploid
Haploid Cells
1 full set of chromosomes
Only one me set is a combination of chromosomes (one from mom and one from dad)
Autosomes
Carry traits that make you who u are you
Sex chromosomes
Carry traits that you who u are and determine you biological sex
Karyotype
Diagram that shows the number and visual appearance of chromosomes in a cell
Sexual reproduction
organisms that reproduce serually (humans) tuse the senelic inbrmation (gametes) tam a
Parents to produceuffspring that are genetic mixture of buth parents
Fertilization
The actual fusion of egg and sperm to form a zygote
Homologous chromosomes
chromosome pairs that have the Same type of genes
-one from mom one from dad
Sister chromatids
2 identical copies of the same chromosomes
Sister chromatids
2 identical copies of the same chromosomes
Purpose of mieosis
Is the process of creating gametes( sex cells that have HALF the normal chromosomes)
Before meiosis
S phase- dna replication
G1 and G2-cell grows and makes proteins
Meiosis 1
Separation of homologous chromosomes
