Non-Mendelian Genetics

In mice, the homozygous mice are black and white. The heterozygous mice are gray. What pattern of inheritance is expressed in fur color in mice?

• complete dominance and recessiveness
• co-dominance
• incomplete dominance

If this image were real, it would represent what type of inheritance?

AB blood type is an example of what type of inheritance?

• complete dominance
• incomplete dominance
• codominance
• polygenic inheritance

I have 1 X chromosome and 1 Y chromosome. What am I?

• Male
• Female

The sex of a child is determined by

• whether the father's sperm contains an x or y chromosome
• whether the mother's egg contains an x or y chromosome
• the age of the parents

An individual's sex is determined by 

• 1 of 23 chromosomes
• 2 of 46 chromosomes
• 4 of 92 chromosomes

Why is the gene for a disease or disorder more likely to be found on the X chromosome than Y?

• The X chromosome has many more genes
• The Y chromosome has many more genes

Males are more likely to suffer from a sex-linked disease or disorder because

• males are the weaker sex
• males have less DNA
• males have 1 X chromosome, so the disorder is more likely to be expressed

When we say that a woman is a carrier for a genetic disease or disorder it means that

• she has 1 gene, but not the disorder
• she has 2 genes for the disorder
• she can pass the gene only to male children
• she can pass the gene only to female children
