Meiosis
The stage of meiosis where crossing over occurs.
What is Prophase 1?
The fraction of the offspring that will be DD in a Dd x Dd cross.
What is 1/4th
The pattern of inheritance is expressed in fur color in mice, where homozygous mice are black and white, and the heterozygous mice are gray.
What is incomplete dominance?
The number and type of daughter cells Meiosis produces.
What is four haploid cells?
The ratio of genotypes that crossing an organism (Aa) with an organism of the same genotype yields.
What is 1:2:1
A single gene that has 3 or more alternative forms
What is multiple alleles?
The definition of crossing over. (Can be in simple terms.)
What is an exchange of information between 2 homologous chromosome which creates a new combination of genes?
The probability of an offspring that is homozygous recessive for all 3 traits, if the parents of a cross are AaBbCc x aaBBcc.
What is 0%?
The type of inheritance shown in cattle offspring that are roan (WR). (their coats contain both white and red hairs)
What is codominance?
The definition of a tetrad.
What is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids?
The number of unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE?
What is 8?
Human eye colors are found on a spectrum that ranges from completely pigmented (dark brown eyes) to a complete lack of pigment (light blue eyes).
The type of inheritance shown in this example.
What is polygenic inheritance?
Disease caused by nondisjunction.
What is Down syndrome, Turners syndrome, Edwards Syndrome?
DAILY DOUBLE!! 🎉
The plant Mendel used to study genetics.
What is peas?
A disease caused by Pleiotropy.
What is sickle cell amemia?
