Question

Which is not true about the first 22 pairs of chromosomes in a karyotype

they determine the gender of the individual
each pair has one chromosome from the father and one from the mother
they are called autosomes
they are homologous meaning each pair has the same size shape, and collection of genes
​

Answer 1

The correct answer is - they determine the gender of the individual.

Step-by-step explanation:

Autosomes are the chromosomes that are numbered or non-sex chromosomes. In humans, there are 22 pairs of autosomes that are numbered from 1 to 22. These chromosomes regulate or control the pattern of inheritance of every characteristic or trait of an organism other than present on the sex chromosomes.

These are homologous chromosomes which means each pair has the same genes and has a similar shape. The gender of an individual depends on the sex chromosome only.
