- Q1Which of these cells is haploid?zygoteliver cellred blood cellsperm cell30s
- Q2What results from meiosis of a diploid cell?genetically different haploid cellsgenetically identical haploid cellsgenetically different diploid cellsgenetically identical diploid cells30s
- Q3What will be the genotypes of the offspring resulting from a genetic cross between two individuals, one of which is homozygous dominant, (TT), and the other heterozygous?50% TT, 50%Ttall Tt50% TT, 50% tt25%TT, 50%Tt, 25% tt30s
- Q4Which statement about the human sex chromosomes is correct?All boys have two Y chromosomesEverybody has at least one X chromosome.Nobody has two X chromosomes.Girls have a Y chromosome and an X chromosome.30s
- Q5The diagram shows the chromosomes in the nucleus of a cell that divides by mitosis. Which diagram shows the chromosomes in the nucleus of one of the daughter cells produced?CBDA30s
- Q6The diagram shows the fusion of gametes to produce a son and a daughter. What are the sex chromosomes in gamete Q and son R?Q - Y R - XXQ - X R - XYQ - Y R - XYQ - X R - XX30s
- Q7A man has three sons. What is the chance of his next child being a son?50%0%25%75%30s
- Q8The diagram shows a cross between heterozygous tall pea plants. Which statement is not correct?The phenotypes of offspring E, F and G are the same.Offspring F and G are both heterozygous.The ratio of different phenotypes in the offspring is 1: 1.Offspring E and H are both homozygous30s
- Q9A genetic cross between two organisms may be shown as Gg × Gg. What does g represent?a recessive chromosomea recessive allelea dominant chromosomea dominant allele30s
- Q10Some fruit flies have orange eyes and others have red eyes. If two orange-eyed fruit flies are crossed, their offspring always have orange eyes. If two red-eyed fruit flies are crossed, their offspring sometimes include both orange-eyed and red-eyed flies. What can be concluded from these observations?We could determine which allele is dominant only by doing a cross that produces a 3:1 ratio.The allele for orange eyes is dominantThe allele for red eyes is dominant.Crossing an orange-eyed fly with a red-eyed fly will produce a 1: 1 ratio in the offspring30s
- Q11What are alleles?different versions of the same genea pair of chromosomestwo genes side by side on the same chromosomethe total number of genes on one chromosome30s
- Q12The diagram shows the sex chromosomes of a woman and of a man. Their genotypes for a recessive sex-linked condition are also shown. What are the chances that their daughter will show the sex-linked condition?75%0%50%25%30s
- Q13The diagram shows the inheritance of ABO blood groups. The blood groups of some of the individuals are given. What could be Priya’s genotype?BACD30s
- Q14What happens to the chromosome number after meiosis and after mitosis?ABCD30s
- Q15Choose the correct answer.CADB30s
