FLOWERING PLANTS AND

GENETICS RE-TAKE REVIEW

FLOWERS The reproductive structures of plants

called angiosperms

OVARY The part of the flower that turns into the

fruit after fertilization

CARPEL The female reproductive structure of

flowers.

STAMEN The male reproductive structure of a

flower

MITOSIS Cell division that results in 2 identical cells

MEIOSIS Cell division that results in 4 cells with ½

the DNA than the original cell

GENES Segments of DNA found in

chromosomes that can control one or more traits

ALLELES Two forms of the same gene inherited

from each parent

HOMOZYGOUS A gene code with matching alleles

TT or tt

HETEROZYGOUS A gene code with differing alleles

Tt or Ss

DOMINANT TRAIT The trait that appears when two

different alleles are present

RECESSIVE TRAIT The trait that seems to disappear when

two different alleles are present

PHENOTYPE An organism’s physical appearanceEx- color of the eyes

GENOTYPE An organism’s gene codeEx-bb or BB

PUNNETT SQUARES A tool used to predict phenotypes and

genotypes

What is the % chanceof the purple flower phenotype?

What is the % chanceof a BB genotype?
