Heritable feature that varies amongst individuals
Plants that produce offspring of the same variety when they self-pollinate
What do we mean when we use the terms monohybrid cross and dihybrid cross?
What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants?
3) How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE?
4) The individual with genotype AaBbCCDdEE can make many kinds of gametes. Which of the following is the major reason?
5) Mendel continued some of his experiments into the F2 or F3 generation to _____.
6) Which of the following statements about independent assortment and segregation is correct?
8) Mendel accounted for the observation that traits that had disappeared in the F1 generation reappeared in the F2 generation by proposing that _____.
Mating 2 true breeding varieties
9) The fact that all seven of the pea plant traits studied by Mendel obeyed the principle of independent assortment most probably indicates which of the following?
Each pair of alleles segregates independently of any other pair of alleles.
Only applies to genes on different, non homologous chromosomes or those far apart on the same chromosome.
alternate versions of a gene
An organism with two identical alleles for a character
refers to a particular gene that has identical alleles on both homologous chromosomes.
It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location.
The position of the genes on each ________ is the same. However, the genes may contain different alleles.
An organism with two different alleles for a gene
Breeding the mystery individual with a homozygous recessive individual
If any offspring display the recessive phenotype, the mystery parent must be heterozygous
Mendel's observation of the segregation of alleles in gamete formation has its basis in which of the following phases of cell division?
Genes that are inherited together because they're located near each other on the same chromosome.
Offspring with a phenotype matching one of the parental phenotypes
Offspring with non parental phenotypes (new combination of traits)
Pairs of homologous chromosomes do not separate normally during meiosis, resulting one gamete receiving two of the same type of chromosome and the other gamete receives no copy
result form the fertilization of gametes I which nondisjunction occurred. Offspring with this condition have an abnormal number of a particular chromosome.
has only copy of a particular chromosome
Has three copies of a particular chromosome.
4 types of changes in chromosome structure
The process by which DNA directs protein synthesis and includes translations and transcription
Catalytic RNA Molecules that function as enzymes and can splice RNA
How something is expressed. Acetyl group attached to an animo acid in a histone tail.
