True or False

When genes are on the same chromosome, the alleles on one of the two homologous chromosomes are considered to be in trans.

Two genes can be syntenic and unlinked.

If recombination rate is high, then a particular combination of alleles is likely to be transferred to the next generation intact.

Solutions

Expert Solution

1. When two genes are on the same chromosome, and if dominant alleles of the two genes  are on one homologous chromosome and recessive alleles of the genes is on the other homologous chromosome it is Cis-linkage.

If a chromosome of the homologous pair has one allele of the two genes is recessive and another is dominant it is called trans - linkage.

The first statement is false.

2. Yes, two genes can be sentenic and unlinked. It is true statement.

Syntenic genes are the genes located on the same chromosome. If the genes are far away on a chromosome, they can behave like unlinked genes.

3. Recombination frequency is the frequency of new combinations. Higher frequency indicates more recombinations. Which means the genes are located far away in the chromosome. When the genes are far away , chances of the genes inherited together is less. The statement is false.
