Heredity

What did Gregor Mendel find out from his experiments?

• An organism's appearance or other detectabe characteristics.
• There must be two sets of instructions for each characteristic
• Each parent gives two sets of genes to the offspring

What is the definition of phenotype?

• An organisms appearance or other detectabe characteristics.
• The traits of an organism and how the organism grows
• Dominant and reccessive alleles
• The genetic makeup of an organism/ the combo of genes for one or more specific traits

Genes are found on

• sex cells
• alleles 
• chromosomes
• ribosomes

What is a pedigree?

• A very important historical event
• An organism with more than one trait
• A diagram that tells you how heredity is passed down through the cells for many organisms
• A diagram that shows the occurrence of a genetic trait over several generations

What combines to make either XX or XY?

• DNA splits into x's
• egg and sperm
• meiosis

What are alleles? 

• segment of DNA that is not used for making the body 
• half of a chromosome
• different versions of a gene

Are recessive traits shown with capital or lowercase letters? 

• Capital
• Lowercase

An organism's appearance is known as it's....

• genotype
• allele
• gene
• phenotype

How many times are chromosomes copied during mitosis?

• twice
• four
• seven
• once

Meiosis did not help explain other inherited traits in Mendel's experiments.

• true
• false
