2

How many chromosomes does a human zygote contain?

2

If a fruit fly zygote has 8 chromosomes, how many chromosomes are in a haploid fruit fly cell?

2

If a haploid chupacabra cell has 50 chromosomes, how many chromosomes will a diploid chupacabra cell have?

The next set of questions is about Mendelian traits.

In certain breeds of dogs, the gene for fur color has two alleles. The dominant allele (G) codes for grey fur and the recessive allele (g) codes for brown fur. A heterozygous grey male is crossed with a brown female. Respond to the following questions about that cross.

0

Snapdragon plants are incompletely dominant for color. They have the phenotypes red, white, and pink. The red and white flowers are homozygous, while the pink flowers are heterozygous. Complete a Punnett square showing a cross between a plant with red flowers and a plant with white flowers..

In some chickens, the gene for feather color is controlled by codominance. There are two alleles: black (B) and white (W). For an individual to be black or white , they must be homozygous (BB or WW) for that allele. An individual that inherits one of each allele will be speckled. Complete a Punnett square showing a cross between a black chicken and a speckled chicken.

Human blood typing is an example of a trait with multiple alleles. It is also an example of codominance. There are two dominant alleles (A & B) and one recessive allele (O). If an individual is heterozygous with an A and B allele, both will be expressed.
