Hint: Try making a Punnett Square to figure it out.

Accepted Answer

long 100% of the offspring.

Answer

short 100% of the offspring.

Answer

long in 50% of the offspring.

Answer

short in 75% of the offspring.

Question 3

A child looks more like one parent than the other because a child only inherits chromosomes from one parent.

Accepted Answer

False

Answer

True

Question 4

A florist has one kind of plant that usually has red flowers (the dominant trait), but sometimes has white flowers (the recessive trait). If she crosses plants A and B as shown here, 50% of the offspring will have red flowers.

Accepted Answer

True

Answer

False

Question 5

A heterozygous orange-flowered plant (O o) is crossed with a homozygous (o o) purple-flowered plant. If orange is a dominant allele and purple is recessive, what color ratio will the flowers of the offspring plants have?

Accepted Answer

2 purple: 2 orange

Answer

1 purple: 3 orange

Answer

4 purple: 0 orange

Answer

0 purple: 4 orange

Question 8

A scientist crossed two fruit flies in a lab. She was studying the transmission of the alleles that affect wing shape. The dominant allele, C, is the allele for curly wings, and the recessive allele, c, is the allele for straight wings. She knew that one of the parent flies was heterozygous and had curly wings (Cc).

Half of the offspring from the cross had curly wings, and the other half had straight wings.

Identify the genotype of the second parent fly. How do you know this?

Accepted Answer

c c

Answer

C C

Answer

C c

Answer

c C
