Cell Cycle
The stage where chromosomes line up in the middle of the cell.
What is metaphase?
What is a dominate allele?
Egg and sperm cells.
What are gametes?
The probability of recessive traits being expressed in the cross of Tt x Tt.
What is 25%
The stage of the cell cycle where two complete and identical daughter cells are formed.
What is cytokinesis?
The number of non-identical daughter cells at the end of meiosis.
What is 4?
The trait that will only be expressed if both alleles are present.
What is recessive?
The proteins that DNA is tightly wrapped around in a chromosome.
What are histones?
The probability of a dominant trait being expressed in the following cross. Tt x tt
What is 50%?
The stage where chromosomes begin to condense to form the traditional X form.
What is prophase?
A cell with only one set of chromosomes.
What is a haploid cell?
What is co-dominance?
Each "arm" of a chromosome.
What are sister chromatids?
The probability of an offspring expressing the recessive trait if a heterogeneous father was mated with a homozygous recessive mother.
What is 50%?
The longest stage of the cell.
What is interphase?
A cell with two complete sets of chromosomes.
What is a diploid cell?
The offspring will have a blended phenotype due to the combination of expressed traits.
What is incomplete dominance?
The variations of traits.
What are alleles?
The probability of a heterogenous parent mating with a heterogenous parent having an offspring expressing a dominant trait?
What is 75%
The stage of mitosis where the chromosomes are pulled apart and head toward opposite ends of the cell.
What is anaphase?
Genes are transferred between chromosomes - creating variation within the chromosomes.
What is crossing over?
The physical characteristics of an organism.
What is phenotype?
The center of a chromosome where sister chromatids are connected.
What is the centromere?
The probability of a homozygous recessive parent and a homozygous dominant parent having an offspring expressing a recessive trait.
What is 0%?
