- Genotype
- the specific alleles (gene) that are inherited
- dominant
- an upper case letter represents which allele?
- Homozygous
- the zygote inherited 2 identical alleles for a single trait
- Karyote
- micrographic display of the homologues pairs of chromosomes.
- Genes
- segments of DNA on chromosomes that code for specific traits.
- Monohybrid cross
- Used to determine if an individual with dominant phenotype is heterozygous or homozygous
- Zygote
- fertilized egg
- Genotype
- EE homozygous dominant (phenotype = unattached earlobes), Ee heterozygous (phenotype = unattached earlobe), ee homozygous recessive = attached earlobes phenotype: These are example of what?
- Allele
- alternate form of a gene for a particular trait
- Heterozygous
- The zygote inherited 2 different alleles for a single trait
- 44
- How many of your chromosomes are autosomes?
- Phenotype
- appearance of an organism regarding a trait (expression of trait)
- xx
- female
- genetic notation
- letters from the alphabet to represent alleles e.g. E = unattached earlobes, e = attached earlobes
- Chromosomes
- humans have 46 (23 that are paired) chromosomes (Made up of DNA): packages of DNA that code for proteins (traits)
- xy
- male
- Gene locus
- the particular location on a chromosome
- 46
- How many chromosomes do you have?
- 23
- How many homologous (aka homologues) pairs of chromosomes do you have?
