What are autosomes?
genes that do not determine the sex of an organism
genes that determine the sex of an organism
chromosomes that do not determine the sex of an organism
chromosomes that determine the sex of an organism
|
What does it mean when genes are described as linked?
they have no influence on inheritance patterns
they are located on the same chromosome and tend to be inherited separately
they are located on different chromosomes
they are located on the same chromosome and tend to be inherited together
|
What is the effect of autosomal linkage on inheritance?
it results in a non-random association of alleles at different loci
it results in a higher number of recombinant offspring
it results in independent assortment of alleles
it results in a random association of alleles at different loci
|
What does the preservation of parental allele combinations across generations indicate?
the genes are located very far from each other on the chromosome
there is a high degree of crossing over
there is no autosomal linkage
there is a high degree of autosomal linkage
|
What is the effect of crossing over on linked genes?
it has no effect on their inheritance
it increases the likelihood of mutations
it brings them closer together on the chromosome
it can separate them, creating new combinations of alleles
|
What does a low number of recombinant offspring indicate?
there is a high degree of autosomal linkage
there is a high degree of crossing over
the genes are located very far from each other on the chromosome
there is no autosomal linkage
|
How does autosomal linkage affect genetic variation in offspring?
it increases genetic variation by producing a high number of recombinant offspring
it has no effect on genetic variation
it increases genetic variation by preserving parental allele combinations
it decreases genetic variation by producing a low number of recombinant offspring
|
What does the term 'chiasmata' refer to?
regions where genes are not linked
regions where genes are linked
regions where crossing over occurs
regions where mutations occur
|
What is the term for offspring that have different combinations of alleles from their parents due to crossing over?
|
