Asthma

Is chromosome number a good predictor of the complexity of the organism?

Yes

The expected number of chromosomes in human body cells is 46. Fruit flies have only 8 chromosomes, mulberry trees have 308, and protists can have thousands. Dogs are in the middle of the range, with 78 chromosomes. How many chromosomes are in the sex cells of each of these organisms?

Always 23

Always half as many in the body cells

Always as many as in the body cells

Always twice as many as in the body cells

Genetic disorders can result from a missing piece of a chromosome. Cri du chat syndrome is caused by a shortened chromosome 5. In French, the name means “cat’s cry”. Babies with cri du chat syndrome make a cry like a kitten. Cri du chat causes many physical and mental symptoms. What is a person with an incomplete chromosome missing?

Many genes

All genes

A body cell

A sex cell

When a plant produces pollen cells with half the chromosomes of the parent cells it has completed:

Mitosis

Meiosis

When a bacterium divides to make two identical daughter cells it has completed:

Mitosis

Meiosis

When a skin cell divides rapidly to replace tissue damaged by a scrape it has completed:

Mitosis

Meiosis

Mitchell’s family has the unusual trait of having an extra finger. Many members of his family were born with an extra finger, which is a recessive trait. At a family dinner, Mitchell’s grandmother helped him sketch a pedigree of the family. Dark-shaded family members were born with an extra finger. No shading indicates people who do not have an extra finger. A question mark means it is unknown. Mitchell is #8 on the pedigree and Mitchell’s grandmother is #2. Based on the pedigree, what do you predict for family members #11, #12, and #13?

Heterozygous recessive with an extra finger

Homozygous recessive with an extra finger

Heterozygous recessive without an extra finger

Homozygous recessive without an extra finger
