When closely placed genes on the same chromosome are inherited together,the phenomenon is known as:

Given below is a highly simplified representation of the human sex chromosomes from a karyotype. The genes $a$ and $b$ could be of

Why did Mendel face difficulties in explaining linked traits?

Sex linkage was first observed by.....

There are three genes $a, b,$ and $c$. The percentage of crossing over between $a$ and $b$ is $20\%$,between $b$ and $c$ is $28\%$,and between $a$ and $c$ is $8\%$. What is the sequence of these genes on the chromosome?
