Answer #1

Chromosomes are the support of genes. Genes present in the DNA are supported by chromosomes. Heredity linked to the gender concerns both the X and Y chromosomes. The phenotype designates the external appearance and the way genes in a cell are expressed. The genotype designates the genetic material of the cell. So, the answer for this question is option A.

    Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic.

    Which of the following statements about maternal effect is true? In maternal effect, reciprocal crosses give identical results but with different ratios among male and female progeny. In maternal effect, the phenotype of the progeny does not necessarily depend on the individual's genotype but on the genotype of the maternal parent. In maternal effect, the genes are linked to the X chromosome. In maternal effect, a trait is transmitted through the ooplasm because the mitochondria and chloroplasts of the zygote...
