Unit 3 List 3 DNA & Heredity KS Flashcards
The process by which a single parent cell splits to form new cells, known as daughter cells
Cellular Division
the female reproductive cell, or gamete
Egg Cell
the study of how cells control gene activity without changing the DNA sequence
Epigenetic
The process by which two gametes (reproductive cells having a single, haploid set of chromosomes) fuse to become a zygote, which develops into a new organism
Fertilization
The complete set of DNA (genetic material) in an organism
Genome
a trait or variants encoded in DNA and passed from parent to offspring during reproduction
Inherited Traits
an organism composed of many cells
Multicellular Organism
the production of new organisms by the combination of genetic information of two individuals of different sexes
Sexual Reproduction
The male reproductive cell, formed in the testicle
Sperm Cell
one of the numbered chromosomes, as opposed to the sex chromosomes
Autosomal
when one allele completely dominates or takes control of the other
Complete Dominance
a cross between two individuals with two observed traits that are controlled by two distinct genes
Dihybrid Cross
the first generation of offspring produced by a set of parents
F1 (first filial)
the result of a cross between two F1 individuals
F2 (second filial)
describes the number of times a genotype would appear in the offspring after a test cross
Genotypic Ratio
