Mitosis
The product of mitosis is
two genetically identical daughter cells
the products of meiosis are
4 genetically unique haploid daughter cells
science of heredity
genetics
outward observable trait of an organism
phenotype
the allele pairs of an organism
genotype
Mitosis does this once and meiosis does this twice
divide
This occurs during prophaseI that enables genetic variation
crossing over
dominant allele
Trait with least probability of appearing in offspring
recessive allele
Heterozygous organisms that carry both dominant and recessive genes
hybrids
mitosis is involved in this while meiosis produces gametes
growth and repair
Meiosis is involved in the production of these
gametes
case in which there are more than two chromosomes formed in an organism
polyploidy
1 TT: 2 Tt: 1 tt is an example of
genotypic ratio
RrTt
RT, Rt, Tr, tr
diploid
Meiosis produces four of these cell types
haploid
diploid
What is the probability of an offspring having white flowere if the parents are yellow flower parent Yy and a white flower parent yy
50 %
This tells you the probability of offspring phenotypes
phenotypic ratio
This occurs during the interphase stage in mitosis unlike into the prophase stage of meiosis
DNA replication
This occurs in meiosis to the chromosomes but does not occur in mitosis (not crossing over) and occurs in prophase
synapsis of homologous chromosomes
a cell that has half a set of chromosomes
haploid
Y is yellow stem, y is green stem, R is rough, and r is smooth
What are the possible phenotypes for offspring given the four traits listed above
yellow and rough stem
green and rough stem
yellow and smooth stem
green and smooth stem
What is the phenotypic ratio for a cross between parent Yyrr and yyRr
