The frequencies of the F2 progeny can be determined by applying this rule

9:3:3:1 is the phenotypic ration produced from this type of cross

True or False: The larger the number of total individual counts in a chi-squared test, the higher the degrees of freedom (df)

The pedigree shown shows three separate rare autosomal conditions in different families. For each pedigree, decide if the condition is better explained as recessive or dominant.

For the cross AAbb x AaBb what are the expected progenies?

A cross between a homozygous yellow line (GG) and a homozygous green line (gg) will result in F1 plants that are heterozygous (Gg) for this trait and produce yellow seeds.
When an F1 plant undergoes meiosis what gamete types will it produce and in what pr

A pea plant is heterozygous for two genes; one controlling height, one controlling color. The genotype is written PpTt. Based on the law of independent assortment, approximately what proportion of the pollen produced by this plant should have the genoty

The dorsal pigment pattern of frogs can be either "leopard" (white pigment between dark spots) or "mottled" (pigment between spots appears mottled). The trait is controlled by an autosomal gene. Males and females are selected from pure-breeding populati

According to Mendels law of segregation this always receives only one of the parents alleles for each gene

Below you will find listed the gamete possibilities for a heterozygous parental strain, state which are correct and which are incorrect:
a) 3/4G 1/4g
b)1/2G 1/2g
c)1/2GG 1/2gg
d)1/2Gg 1/2Gg
e)3/4g 1/2G
f) 1/2g 1/2g

What is the probability that an F2 seed chosen at random will be yellow?
What is the probability that an F2 weed chosen at rending from among the yellow seeds will breed true when selfed?
What is the probability that three F2 seeds chosen at random will i
