Meiosis Flashcards
what is meiosis?
a type of cell division responsible for producing gametes (egg/sperm)
meiosis produces gametes so that each parent can…
make an equivalent contribution of genetic information to each offspring
diploid condition is
cell in which the nucleus contains two sets of chromosomes
a haploid condition is
cell in which the nucleus has one set of chromosomes
a gamete is a
a sex cell
a trait..
an inherited characteristic
a gene…
a segment of DNA that encodes for a particular trait
an allele…
an alternate form of a gene
a chromosome…
the cellular structure where DNA is housed
sister chromatids…
one of the two identical parts of a duplicated chromosome
a homologous chromosome…
two chromosomes that make a matched pair in a diploid cell
dominant allele is…
the allele that determines the phenotype expressed
recessive allele is…
an allele that has no effect on the phenotype
genotype is…
the actual genetic make-up of an organism
phenotype is…
the physical expression of a genotype
the law of segregation of alleles…
when the gametes are formed by an individual only one member of each allele pair is included in a gamete
the law of independent assortment of alleles…
all possible kinds of gametes will be formed in equal amounts
the law of dominance…
whenever the 2 alleles of a pair in a given individual differ, the dominant one will be expressed
what are homologues?
1 member of a sister chromatid
synapsis is the process by which…
sister chromatids form tetrads
meiosis 1 is known as the
reduction division
the parent cell is AKA
the primary sex cell
mendel’s law of segregation of genes
one gene is separated into a separate cell from the other gene
mendel’s law of independent assortment of alleles
pair of homologous chromosomes sort independently from one another
mendel’s law of dominance
only one member of a pair of alleles will be expressed
