1. Haploid cells:

1. Are representative of all cells in body
2. Occur during mitosis
3. Occur during meiosis
4. Possess paired chromosomes

1. Disease hemophilia results from:

1. Dominant gene on X chromosome in males
2. Recessive gene on Y chromosome in males
3. Recessive gene on X chromosome in males
4. Dominant gene on Y chromosome

1. The human genome consists of:

1. DNA, most of which encodes for proteins
2. DNA, most of which does not encode for proteins
3. Proteins, which encodes DNA
4. RNA, most of which does not encode proteins

1. A gene is:

1. Sequence of DNA nucleotides coding for one protein
2. Sequence of amino acids
3. A chromosome
4. Sequence of RNA nucleotides coding for one protein

1. Genetics is study of:

1. Sperm & egg
2. Effect of environment on our health
3. Inheritance
4. DNA

1. In a human zygote, the 46 chromosomes:

1. All come from sperm cell
2. Half comes from DNA & half from RNA
3. Half comes from sperm cell and half from egg cell
4. All come from egg cell

1. The two types of chromosomes are:

1. Autosomes & allosomes
2. Sex chromosomes & allosomes
3. Sex chromosomes & autosomes
4. X & Y chromosomes

1. In an autosomal inheritance where dominant gene is expressed,all offspring will show dominant homozygous if:

1. Trait is sex-linked
2. Both parents are dominant homozygous
3. Both parents are dominant heterozygous
4. One of the parent is dominant heterozygous

1. In a sex-linked hemophilia disease due to a recessive gene, amating of homozygous female non-hemophilia  withhemophilia male  will result in:

1. 100% females with hemophilia
2. 100% males will not be hemophilia
3. 50% males will be hemophilia
4. None of offspring will be hemophilia

1. An individual with same gene in an allele is said to be:

1. Heterozygous
2. Homozygous
3. Haploid
4. Hemizygous
