The descendants of Mohan and Begum are all yellow tigers, indicating that white is recessive and yellow is dominant in coat color, and the genomes controlling the coat color of the two tigers are homozygous. If a stands for dominant gene and a stands for recessive gene, the generation process of offspring white tiger is as follows:
(1) The morphological characteristics, physiological characteristics and behavior patterns of organisms are called traits, the phenomenon that biological traits are passed on to offspring is called inheritance, and the differences of traits between parents and offspring and between offspring individuals are called variation; Compared with Begum, the yellow tiger cubs produced by Mohan mating with Begum have the same traits as their parents and belong to heredity. Compared with Mohan, Huang Huzai is the difference between parents and offspring, which belongs to the variation phenomenon. Therefore, compared with Begum and Mohan, yellow tiger cubs show biological inheritance and variation respectively.
(2) Different manifestations of the same trait in the same species are called relative traits, and the yellow and white color of Bengal tiger is a pair of relative traits;
If A and A are used to represent the dominant and recessive genes controlling this pair of traits, then the genetic composition of the white tiger can be seen from the genetic map, which is AA.
(3) According to the genetic map, the probability that the offspring of Mohan and Lida are white tigers is 50%.
So the answer is:
(1) inheritance; change
(2) relative; alcoholic anonymous
(3)50
