kan otype (a chromosome display) would be unable to determine A) eye color C) Turner syndrome 5) A B) syndrome D) sex INTERPHASE BEFORE MEIOSIS MEIOSIS II MEIOSISI 36) The above figure shows that A) meiosis results in the formation of four haploid daughter cells B) fertilization results in four haploid daughter cells C) meiosis forms diploid gametes D) the human 2n number is 4 37) The karyotype above shows A) Turner syndrome B) trisomy 21, a cause of Down syndrome C) trisomy 21, a cause of Klinefelter syndrome D) abnormal sex chromosomes 35) 36)

Explanation / Answer

Answer:

35. (A) Eye color

Explanation:

A karyotype can determine only large chromosomal abnormalities. Eye color is a polygenic trait controlled by multiple genes within chromosomes, so it cannot be determined from a karyotype.

36. (A) Meiosis results in the formation of four haploid daughter cells.

Explanation:

Meiosis is the process of formation of haploid sperm cells and ovum. A diploid germ cell undergoes meiosis to form 4 haploid daughter cells.

37. (B) Trisomy 21, a cause of Down's syndrome

Explanation:

Trisomy 21 or Down's syndrome is a result of the presence of chromosome 21 in triplicate rather than the usual matched pair of chromosomes. This birth defect results in low IQ, hearing and visual impairments, heart defects and characteristic facial features.
