Answer and Explanation:
Typically, sea turtles lay around 110 eggs per clutch. However, only a small fraction of the hatchlings survive to reach the ocean. Subsequently, an even fewer number are able to produce their own young.
- Overpopulation
All zebras possess stripes, yet no two zebras exhibit identical stripe patterns.
-Variation
A lemur species named aye-ayes feature extended, slender middle fingers that enable them to probe into tree crevices to extract insects for food.- Adaptation
Answer:
Sister chromatids are identical copies of chromatids from chromosomes. They are typically produced through the semi-conservative replication of a single chromosome's DNA. Thus, they can be viewed as'photocopies' of the original parental chromosomes, linked together at the centromere.
They are entirely identical in every aspect, sharing the same genes and allele configurations.
Still, minor variations can occur between the identical sister chromatids due tomutations fromerrors during replication, and differences can also arise in the lengths of telomere repeats.
Non-sister chromatids differ as they arise from separate haploid sex cells during fertilization. These chromatids come from distinct parents and possess different genetic compositions since they do not lie on the same homologous chromosomes. This is why crossing-over results in genetic variation.
However, they may still exhibit genetic similarities if they are part of homologous chromosomes. This is because Synapsis of the bivalents in these chromosomes permits the exchange of genetic material through crossing-over between non-sister chromatids, thereby sharing identical genetic traits.
