Mendel worked with this type of plant.
What is the pea plant?
Mendel’s vocation (job) made him one of these.
What is a monk?
One of Mendel’s principles states that some alleles are _________ while others are _________.
What are dominant and recessive?
One of Mendel’s principles states the inheritance of biological characteristics is determined by _______ that we get from our parents.
What are genes?
What does it mean for a plant to be pure breeding?
2 of the same alleles
This describes a genotype whose alleles are identical.
What is homozygous?
This describes the weaker of two alleles – the one that is masked.
What is recessive?
This is a physical description of a trait based on the genotype of an organism.
What is the phenotype?
This is one form of a gene.
What is an allele?
This describes two similar chromosomes that line up together during metaphase I.
What is homologous?
A word to describe a cell having chromosomes in pairs (double).
What is a diploid?
This type of inheritance results in offspring who have a mix of the two traits. (Red + white = pink)
What is incomplete dominance?
This type of inheritance takes more than one pair of genes to code for the trait.
What is polygenic?
How many chromosomes are in your blood cells? Are they haploid or diploid?
Which parent determines the sex of the child & why?
Green (G) is dominant over white (g) and round (R) is dominant over wrinkled (r).
What is the genotype of an individual heterozygous for both traits?
What is GgRr?
What is the probability of offspring having the recessive phenotype when homozygous dominant is crossed with homozygous recessive.
BB x bb
What are the gametes that are formed from an individual with the genotype GgRr?
GR, Gr, gR, and gr?
This type of cross has 16 possible outcomes.
What is a dihybrid cross?
This is a haploid cell used in sexual reproduction.
What is a gamete, egg, or sperm cell?
This term describes a type of cell reduction division that results in 4 haploid cells.
What is meiosis?
This is one instruction found on the DNA.
What is a gene?
During which phase of meiosis do spindle fibers separate the homologous chromosomes?
This term describes 4 chromatids that join together during prophase I
What is a tetrad?
