PEAS AND STUFF
a reproductive cell
what is a gamete
the chance an event will occur
what is probability
one allele is not completely dominant over the other. red and white is pink
what is incomplete dominance
contains 2 sets of homologous chromosomes, normal cells
what is diploid
the study of heredity
what is genetics
offspring that have a combination of genes, heterozygous
what is a hybrid
having 2 different alleles for a gene, Aa
what is heterozygous
a trait that is controlled by 2 or more genes
what is a polygenic trait
chromosomes where one set comes from male parent and one set comes from the female parent
what is homologous
a specific characteristic of an individual
what is a trait
a factor that is passed from parent to offspring
what is a gene
having 2 identical alleles for a gene, AA or aa
what is homozygous
when both alleles are completely expressed. red and white gives you red and white spotted
what is codominance
process where haploid reproductive cells are created
what is meiosis
46 chromosomes
what is the haploid chromosome number in humans
one of a different form of a gene
what is an allele
the genetic makeup of an organism, AA Aa aa
what is genotype
having a single set of chromosomes. reproductive cells
what is haploid
where homologous chromosomes exchange portions of chromatids with one another.
what is crossing over
the separation of alleles during gamete formation
what is segregation
some alleles are dominant and some are recessive
what is the principle of dominance
traits segregate independently from each other
what is independent assortment
a gene that has more than 2 alleles, eye color, hair color
what is multiple alleles
when the male gamete joins with the female gamete to form a zygote
what is fertilization
the physical characteristics of an organism
what is phenotype
