Pea Plants
Male part of flower that produces pollen
What is the stamen?
Gene pairs separate during gamete formation
What is the law of segregation?
When an organism has a genotype with two different alleles
What is hererozygous?
What is the probability that an offspring would express a heterozygous genotype if the offspring was produced from a cross between two heterozygous parents (assuming simple Mendelian inheritance)?
2/4 = 1/2 = 50%
A type of trait where one phenotype is determined by multiple genes
What is a polygenic trait?
Female part of flower
What is the pistil?
Gene pairs separate during meiosis without influencing other gene pairs separating
What is the law of independent assortment?
The genotype of plants that are true-breeding for a specific trait
What is homozygous?
What is the probability that an offspring would express a recessive phenotype if the offspring was produced from a cross between one homozygous dominant parent and one heterozygous parent (assuming simple Mendelian inheritance)?
0%
A type of trait where heterozygotes express a blend of the two alleles
What is incomplete dominance?
The true breeding plants that Mendel used for his first cross
What are the P generation?
Heterozygotes express one allele and not the other
What is the law of dominance?
The phenotype of a heterozygote based on simple Mendelian inheritance
What is the dominant phenotype?
What is the probability that an offspring would express a recessive phenotype for two traits if the offspring was produced from a cross between two parent who were both heterozygous for both traits?
1/16 (6.25%)
A type of trait where heterozygotes express both alleles simultaneously
What is codominance?
The hybrid offspring of Mendel's first cross
What are the F1 generation?
A type of inherited trait that can be identified by a pedigree that shows two parents without a specific trait with a child that has that particular trait
What is a recessive trait?
The possible gametes of an individual with a RrTT genotype
What is RT and rT?
What is the probability of a AB phenotype in an offspring of parents who both have AB blood?
50%
When more than two possible versions of a gene exist in a population
What is multiple alleles?
The phenotypic ratio of Mendel's F2 generation
What is 3:1?
A type of inherited trait that can be identified by a pedigree that shows two parents with a specific trait with a child that does not have that particular trait
What is a dominant trait?
The two main factors that impact phenotype
What is genotype and the environment?
What is the probability of an albino mouse in the offspring of a BbCc x bbCc cross if albinism was due to a recessive c allele that is epistatic to the b gene?
25%
A type of trait that shows predominantly male inheritance primarily passed from non-expressing carrier mothers
What is an x-linked recessive trait?
