DNA
A structure made of tightly wound DNA.
What is a chromosome
The purpose of Mitosis
What is growth/Healing/creating new cells/cell division.
The type of cells created during Meiosis.
What are reproductive cells.
The capital letter in a genotype means the trait is _______.
What is dominant.
Links together to create the basic structure of DNA.
What is a nucleotide
What are 2 cells.
The resulting number of cells by the end of Meiosis.
What are 4 cells.
The trait is seen only when both parents provide this allele.
What is a recessive trait
The traits that are observe/seen in the organism.
What is phenotype
A sequence of nucleotides that code for a specific allele.
What is a gene.
The type of cells replicated in Mitosis
What are Somatic cells.
The number of chromosomes in each cell by the end of Meiosis.
What are 23 chromosomes in each cell.
What we call the offspring when they have Tt for their genotype.
What is heterozygous
What is haploid
Two identical chromosomes held together by a centromere
What are sister chromatids
The phase in mitosis where chromosomes line up down the middle and attached to spindle fibers.
What is metaphase.
During Metaphase, these type of chromosomes line up down the middle.
What are homologous chromosomes
What we call an organism that as has BB for their genotype
What is homozygous dominant
When chromosomes randomly line up during the first round of meiosis, increasing variation in offspring.
What is random assortment
Pairs of chromosomes that carry the same genes in the same order, one inherited from the mother and one from the father.
What are homologous chromosomes
The phase where chromosomes tighten up and replicate.
What is interphase.
When homologous chromosomes trade parts, increasing variation.
What is crossing over
The Mendelian principle that states "A heterozygous individual will show the dominant phenotype".
What is the Law of Dominance
This happens during telophase, when the cell membrane pinches off, and cytoplasm separates to create two new cells.
What is cytokinesis
