Answer:

Homologous chromosomes carry the same genes and have the same shape and length, so all the choices are correct.

Explanation:

The homologous chromosomes are so called because each of them has the same DNA molecule, giving rise to the same genes, distributed in the same location within the chromosome.

Somatic cells are diploid, which means that the genetic information that determines specific characteristics is distributed in pairs. Each of the chromosomes that form a pair comes from the father and mother, and the members of a pair are known as homologous chromosomes.

The homologous chromosomes are <u>characterized by having the same shape and size, and contain the same genes</u>, although the information contained in them —the alleles— may be different. Hence the possibility that one allele is dominant and another recessive on two chromosomes of a pair.

No eggs.  Mammals have well developed offspring that they can keep it safe inside their body until the time it is ready to be in the outside world.

Four legs under the body. It allows mammals to be highly developed when it comes to speed.

Fur. It protects the mammals’ skin.
