Genetic- so, OK, maybe they're different alleles, a Hey, Sal, so- let me write this down, in mammals it's Whether it turns into a male or female or other environmentalĮspecially mammals, of which we are one example, it'sĪ genetic basis. Temperature in which the embryo develops will dictate Not all reptiles, butĬertain cases of it. Some types of reptiles, it's environmental. Question, how is gender determined in an organism? And it's not an obvious answer,īecause throughout the animal kingdom, it's actuallyĭetermined in different ways. Playlist, you're probably wondering a very natural But, I have summarized all the essentials. If none of these work, heterozygotes for x-linked recessive (or dominant) will have an intermediate phenotype, somewhere between normal and diseased. In others, such as colour blindness, the few cells expressing the normal phenotype compensate for the others expressing diseased phenotype (in this case, the phenotype is colour sensitivity of cones in retina). This escape is quite well-documented in certain cases. Such locations may escape lyonization (X-inactivation) and might still transcribe proteins even if they are on the x-chromosome chosen for inactivation. Many a times, when the disease-gene is at a specific locus. In haemophilic females, there is some deficiency of the clotting factors and this deficiency varies greatly in different females. The answer is that heterozygous carrier females do express some symptoms of the disease, but the few cells where the functional allele is not inactivated produce enough protein to prevent a full-blown syndrome, and in many cases, keeps the disease un-noticeable. I had this question from quite a long time.
