23pairs in total
1pair of sex chromosome
44 autosomes and 2 sex chromosomes total 46 chromosomes
i. india has low sex ratio as a female child is not well come in many families because of tertition. therefore female infanticide is precticed in some parts of the country
Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype.
Hi ! Let me help u with the answer.
In metaphase discontinuous fibres radiate out from two spindle poles and get connected to the disc shaped structure at the surface of the centromere called kinetochores. These are called chromosome fibres or tractile fibrils.
In female there r 2 X chromosome nd in male one X nd 1 Y chromosome.
Better question try again
Wheat, Triticum aestivum, has basic chromosome number is n = 7; thus the hexaploid species (Triticum aestivum) have 6n = 42. Haploid chromosome number is the one present in gametes of that organism; gametes contain half the chromosomes of the somatic cells. Thus, haploid chromosome number of hexaploid wheat is 21. This makes options A, B and C incorrect. Nullisomy is absence of one complete pair of homologous chromosomes (2n-2). Thus, nullisomic hexaploid wheat is 42-2 = 40. This makes options A and C incorrect. Monosomy is absence of a single chromosome from a diploid cell (2n-1); therefore, monosomic hexapoid wheat has 42-1 = 41 chromosomes. A diploid cell with an extra chromosome is trisomic (2n+1); thus, total number of chromosomes in a trisomic hexaploid wheat is 42+1 = 43. This makes option D correct answer.
statement 3rd is wrong frequency is not inversely proportional to distance
