Unit 6 Genetics: Part 2

Gregor Mendel concluded that traits are

• Not inherited by offspring

• Inherited through the passing of factors from parents to offspring

• Determined by dominant factors ONLY

• Determined by recessive factors ONLY

The father of genetics is

• Charles Darwin

• Alexander Fleming

• Gregor Mendel

• James Watson

The chemical factors that determine traits are called

• Alleles

• Traits

• Genes

• Characters

An organism that has inherited two of the same alleles of a gene from its parents is _________ for that trait.

• Hereditary

• Heterozygous

• Homozygous

• A mutation

When you flip a coin, what is the probability that it will come up tails?

• 25%

• 75%

• 50%

• 100%

The color of a dog’s coat is the dog’s…

• Dominance

• Genotype

• Phenotype

• Pedigree

If you made a Punnett Square showing Mendel’s cross between true-breeding tall plants and true-breeding short plants, the square would show the offspring had…

• The genotype of one of the parents

• A phenotype that was different from that of both parents

• A genotype that was different from both parents

• The genotype of both parents

Situations in which one allele for a gene is not completely dominant over another allele for that gene are called

• Multiple alleles

• Incomplete dominance

• Polygenic Inheritance

• Multiple genes

 A heterozygous tall pea plant is crossed with a short plant. The probability that an F1 plant will be tall is?

• 25%

• 50%

• 75%

• 100%

An organism’s physical appearance, or visible traits. 

• Genotype
• Phenotype
• Beanotype
• Notype
