13 Οκτ 2021 · We deployed Ocean Instruments SoundTrap hydrophones models ST300 STD and ST500 STD (frequency range for both models 20 Hz to 60 kHz ± 3 dB) in three locations in the northern GOA (Fig. 1). One...

Here we use morphological traits, nitrogen stable isotope ratios and tooth wear to characterize two disparate types of North Atlantic killer whale. We find a highly specialist type, which reaches up to 8.5 m in length and a generalist type which reaches up to 6.6 m in length.
24 Δεκ 2022 · This chapter developed the relationship between allele frequencies and genotype frequencies within a generation and among relatives. Under random mating, we derived expectations of the genotype frequencies (Hardy-Weinberg), and we can identify deviations away from these expectations.
What it means for genes to be linked. How to determine recombination frequency for a pair of genes.
17 Σεπ 2024 · When a novel gene or locus is identified by mutation or polymorphism, its approximate position on a chromosome can be determined by crossing it with previously mapped genes, and then calculating the recombination frequency.
2.1 The Hardy-Weinberg equilibrium. The most useful starting point is the null situation where two alleles are present at an autosomal locus in a popUlation and no forces are acting to change their frequency.
2 Φεβ 2019 · Understanding and quantifying such demographic aspects of a wild population is crucial to fully understand the gene flow that is occurring, especially if gene frequencies differ between the focal population and the population from which migrants have arrived.
