sorry really late need to study really tired from basketball don't blame me if i messed up on stuff all of unit D some stuff are represented by lines because if I wrote it.. it would sound really perverted (;-_-)

- upper tip of the pistil of the flower receives the pollen
- meiosis
- the process that occur in a s__ cell (______ and egg) by which the number of chromosomes are reduced in half
- random
- by chance, like the flip of a coin
- Codon
- the three letter code of bases on the messenger RNA that codes for one amino acid
- DNA nitrogen bases

- Anti-codon
- the three letter code of bases on the transfer RNA that matched up with the codon on the messenger RNA
- pedigree
- a chart or "family tree" that tracks which members of a family have a particular trait
- diversity
- A wide variety of traits that are expressed in living things primarily due to reproduction
- genetics
- the scientific study of variation and heredity
- mutation
- Types include substitution,duplication, insertion, and deletion of chromosomes can be caused by: environmental agents (e.g the sun) mistake during DNA replication
- phenotype
- an organism's physical appearence or visible trait
- MRNA
- RNA that copies the code message from the DNA in toe nucleus and carries the message in the cytoplasm
- style
- narrow elongated part of the pistil between the ovary and the stigma
- offspring
- product of reproduction, a new organism produced by one or more parents
- characteristics
- A physical attribute of an organism such as hair color, height, color pattern ect.
- s reproduction
- the reproductive process that involves two parents who combine their genetic material to produce a new organism in which differs from both parents
- a reproduction
- the reproductive process involves only one parent and produces offspring that are identical to the parents( you all know what I mean)
- TRNA
- Carries amino acids and adds them to the growing protein at the ribosome
- genes
- a segment of DNA on a chromosome that codes for a specific trait
- pistil
- female reproductive part of a flower
- Amino-acid
- The building blocks of proteins; 1 codon= 1 amino acid; 100s to 1000s amino acids = 1 protein ;1 gene = 1 protein
- heterozygous
- having two different alleles for a trait
- stamen
- male reproductive part of a flower
- mitosis
- cell division creates two daughter cells identical to the original parent cell
- clone
- an organism that is genetically identical to the organism from which it is produced
- heredity
- the passing of traits from parents to offspring
- probability
- the likelihood that a particular event will occur
- chromosomes
- rod shaped cellular structure made of condensed chromatin DNA condensed into chromosomes just before cell division
- "nature vs. nurture"
- The debate regarding how much influence GENES and the Environment have on an individuals traits
- incomplete dominance
- a pattern of inheritance when the combination of a recessive allele and dominant allele (heterozygous) is expressed as a blend of the two traits (Ex. R=red, r=white, Rr=pink)
- fertilization
- the joining of a s____ cell and an egg cell
- traits
- a specific variation of a characteristic that an organism can pass on to it's offspring through it's genes
- recessive
- an allele that is masked when a dominant allele is present
- inherited
- transmitted through genes from parents to offspring
- anther
- the upper part of the stamen where the pollen is produced
- co-dominance
- A pattern of inheritance when two alleles of a gene are neither dominant or recessive, the two alleles are both expressed (Ex. B=black feathers b= white feathers Bb= black and white feathers)
- filament
- stalk like part of the stamen that supports the anther
