Match the features with their corresponding concept:
Genes are physically linked ↔️ Autosomal linkage
Genes are located on different chromosomes ↔️ Independent assortment
Why are linked genes more likely to be inherited together?
They are physically linked
Recombination frequency is calculated based on the frequencies of parental and recombinant phenotypes.
What does recombination frequency measure?
Likelihood of genes co-inherited
What is one mapping unit equal to in recombination frequency?
1%
Autosomal linkage occurs when genes are located on sex chromosomes.
False
Autosomal linkage violates Mendel's law of independent assortment.
True
Genes located far apart on the same chromosome are more likely to exhibit linkage than genes located close together.
False
What is the phenotypic ratio for two unlinked genes under independent assortment?
9:3:3:1
Match the distance between genes with the recombination frequency:
Close ↔️ Low
Far apart ↔️ High
Genes farther apart on a chromosome have a higher recombination frequency than genes closer together.
True
What is the map distance between two genes with a recombination frequency of 15%?
15 cM
What happens to genes located on the same chromosome during gene linkage?
Inherited together more often
Recombination frequency is directly related to the distance between genes on a chromosome.
False
Sex-linked traits affect males and females equally.
False
What phenotypic ratio is expected under independent assortment in the F2 generation of two heterozygous parents?
9:3:3:1
How many recombination frequencies are equal to one mapping unit?
1%
Autosomal linkage is in contrast to independent assortment.
Gene linkage refers to the phenomenon where two or more genes are located on the same autosome.
Gene linkage contradicts Mendel's law of independent assortment.
The recombination frequency is inversely related to the distance between genes on a chromosome.
True
The formula to calculate recombination frequency is: \text{Recombination Frequency} = \frac{\text{Number of recombinant offspring}}{\text{Total number of offspring}}</latex>offspring
Map distance is calculated in centimorgans, where 1% recombination frequency equals 1 centimorgan
Autosomal linkage is in contrast to independent assortment, where genes on different chromosomes are inherited independently
Autosomal linkage alters the 9:3:3:1 ratio because linked genes are inherited together
