According to the gene-chromosome theory, witch statement is
a) genes are presented only in human gene-chromosome
b) genes are arranged in linear sequence on a chromosome
c) alleles are located on non-homologous chromosome
d) mutation occurs mainly in sex cells
e) none of the above
2 chromosome theory
6 x chromosome
7 y chromasome
The correct matching options are as follows-
1.Any pair of chromosomes other than the sex chromosomes- autosomeExample- Chromosome 1 to 22 in human beings.
2.Idea that the behavior of chromosomes explains the inheritance of genes- chromosome theory
3.Having chromosomes in homologous pairs- diploid.
Diploid means presence of two sets of chromosomes ( called homologous chromosomes) in the individual.
4. Having one half of each pair of homologous chromosomes-haploid.
Haploid refers to the single set of chromosmes ( like sperm and eggs cells, which are haploid).
5.The presence of different genes on the same chromosome- linkage
6.A sex chromosome; two present in females and one present in males- X chromosome
Females have XX genotype whereas males have XY genotype.
7.A sex chromosome found in males; influencing the degree of maleness- Y chromosome .
Y chromosome is responsible for the male characteristics.
1. Meiosis 1.
2. Meiosis 2.
4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.
B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;
B)Mendelian genes are at specific loci on the chromosome and,in turn, segregate during meiosis.
B. The arrangement of chromosomes at metaphase of meiosis depends on the arrangement of all other chromosome pairs.
Each chromosome pair during meiosis arrange itself on the equator of the cell. Here, one homologous chromosome pair arranges itself on the equator independently of other homologous pairs. This random and independent arrangement of chromosomal pairs results in their random and independent segregation during anaphase.
wow that's a lot
a) genes are presented only in hu...
