GENETICS Flashcards
(42 cards)
It is the branch of biology that studies genes, heredity, and variation in living organisms.
Genetics
are specific sequences of DNA that serve as instructions for building proteins. it is also mendel’s observed “factors”
Genes
are essential molecules that perform various functions in the body, such as enzyme activity, structural support and immune defense.
Protein
Each gene consists of a unique sequence of nucleotides, what are these?
- Adenine
- Thymine
- Guanine
- Cytosine
It explores how traits are passed from parents to offspring through DNA and how genetic differences contribute to diversity among individuals.
Genetics
Parts of Chromosome X
- Telomeres
- Short and Long Arm
- Centromere
- DNA Molecule
- Sister Chromatids
are long, thread-like structures made of DNA and proteins.
Chromosomes
Human have ___ chromosomes which are ___ pairs each.
46 ; 23
It is the process by which traits and characteristics are passed from parents to offspring through genes.
Heredity
These are traits that are manifested.
Dominant Traits
These are traits that are often masked off.
Recessive Traits
Different Alleles
Heterozygous
Two Identical Alleles
Homozygous
It is controlled by genes.
Heredity
One of two or more alternative forms of gene in the same location on chromosome
Allele
It determines an organism’s genotype
Genes
It determines organism’s phenotype
Allele
It is an observable traits of an organism
Phenotype
Genetic constitution that an individual inherits; it tells the body how to things
Genotype
In a heterozygote, one trait will conceal the presence of another trait for the same characteristic.
Law of Dominance
Fertilization between two true-breeding parents that differ only in the characteristic being studied. Results are referred to as ______________.
Monohybrid Cross
Punnett Square was devised by
Reginald Punnett
states that each organism carries two alleles for each trait, but only one allele is passed on to offspring during gamete formation.
Law of Segregation
A way to determine if an organism expressed a heterozygous or homozygous dominant trait.
Test Cross
