Comparative analysis of the polymorphism of C segments on chromosomes 1, 9, 16, and Y was conducted in 50 normal boys and 50 normal girls. Quantitative methods revealed that the mean lengths of C segments, their variability, and their distribution on the chromosomes mentioned are quite identical in the two groups. Methodological problems related to the study of chromosome polymorphism are discussed.

We investigate the representations learned by vision and language models in tasks that require relational reasoning. Focusing on the problem of assessing the relative size of objects in abstract visual contexts, we analyse both one-step and two-step reasoning. For the latter, we construct a new dataset of threeimage scenes and define a task that requires reasoning at the level of the individual images and across images in a scene. We probe the learned model representations using diagnostic classifiers. Our experiments show that pretrained multimodal transformer-based architectures can perform higher-level relational reasoning, and are able to learn representations for novel tasks and data that are very different from what was seen in pretraining.
