Compare and contrast properties of sister chromatids and homologous chromosomes.
lubasha [3.4K]

Answer:

Explanation:

Sister chromatids are regarded as replicated chromosomes. Sister chromatids are two identical copies of chromosomes held at the centromere that are formed as a result of replication. They are identical in the sense that they contain same alleles/gene sequence of the same genes.

Homologous chromosomes, on the other hand, are similar (in length, centromere position) but non-identical chromosomes. Homologous are non-identical in the sense that they may contain different alleles of a gene and are received from each parent. homologous chromosome contain four chromatids; two of which are sister chromatids and non-sister to the other two.

Both undergo meiosis where homologous chromosomes separate in meiosis I while sister chromatids separate in meiosis II but only sister chromatids undergo mitosis.

A newly discovered animal reproduces slowly. It has only one offspring each time it reproduces. Which reproductive strategy does
Marizza181 [45]

Answer:

C: K Strategy

Explanation:

The best choice will be C- K strategy because this type of strategy involves greater investment from parents into their offspring. These organisms are mostly higher organisms which reproduce slowly and ensure the maximum survival of their offspring. They compete strongly with other organisms and invest more in their survival by producing fewer quality offspring that have more survival opportunities.

Example of K-selected species include  larger mammals (such as primates and horses), birds and larger plants. Unlike their opposite R-selected specie which produce large number of offspring, K selected specie are called in Equilibrium wile R-selected species are called as opportunistic.

Thank you!
