The type of gene that always shows itself is called aHomozygous geneRecessive genePowerful geneDominant gene5. Which of the following cross gives a typical dihybrid test cross ratio?Yyrr x YyrrYyRr x YyRrYyrr x yyRrYyRr x yyrr6. Cause of Down's syndrome isSex linked inheritanceNondisjunction of chromosomesIinkageCrossing over7. Darwin produced the first known theory to explain evolutionTrueFalse8. Heterozygous meansHaving two of the same genes for a certain traitNone of the aboveHaving two genes for a trait that are differentHaving a zygous that is hetero9. Genes of a flower colour in Mirabilis jalapa show incomplete dominance. In a cross between red and white flowered plant, all the F, plants are pink flowered. If these plants are self pollinated, the phenotypic ratio in the F 2 generation will be1 : 2 : 11 : 19 : 3 : 3 : 13 : 110. What does heterozygous meanan allele that is only expressed if there is no dominant allele presenthaving two identical alleles of the same genehaving two different alleles of the same geneone out of two or more versions of a gen11.
