Bio 240 Unit 3

Diplod cells - The presence of two daughter cells and contains identical chromosomes from each parent

Haploid cells - The presence of four daughter cells and contains a single set of unique chromosomes

Meiosis - a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

Mitosis - a process that allows a cell to divide into two identical daughter cells

Prophase - the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Metaphase - the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell.

Anaphase - the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Telophase - when chromosomes move in opposite directions so two new cells can be formed from one.

purpose in animal body

# daughter cells

haploid or diploid daughter cells (final)

#cell division

# dna replications

tetrad present?

identical daughter cells?

mitosis

-somatic cells do this to grow and repair cells and enable a zygote to develop into a multicellular adult

true-breeding - the ability to pass down specific traits to its offspring. (Purebreds)

homozygous traits - having two identical versions of a gene (YY, yy)

heterozygous traits - having two different versions of a gene (Yy)

alleles - one or two more alternative forms of a gene that arise by a mutation

phenotype - the observable characteristics of an organism (physical, behaviors, and development)

genotype - the genetic makeup of an organism

monohybrids - a heterozygous hybrid with respect to a specific gene
