dihybrid cross
Dihybrid cross is a pranit cross between two different lines that differ in two observed traits

gamete
A gamete is a cell that fuses with another cell during fertilization in organisms that sexually reproduce

dominant trait
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus
Got it
locus
A locus in genetics is the position of a gene on a chromosome
Got it
genotype
The genotype is the part of the genetic makeup of a cell, and therefore of an organism or individual, which determines a specific characteristic of that cell/organism/individual

Autosomes
An autosome is a chromosome that is not an allosome
sex chromosomes
A sex-determination system is a biological system that determines the development of sexual characteristics in an organism
crossing over
Chromosomal crossover is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes during sexual reproduction
base pairs
A base pair is a unit consisting of two nucleobases bound to each other by hydrogen bonds
polynucleotide
A polynucleotide molecule is a biopolymer composed of 13 or more nucleotide monomers covalently bonded in a chain
recombination
Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent
double helix
In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA
nucleotides
Nucleotides are organic molecules that serve as the monomers, or subunits, of nucleic acids like DNA and RNA
