How do you know which trait is dominant and recessive?

• Consult a horoscope
• Use a Punnett square
• Dominant allele is lower case and recessive is capital

• Dominant allele is capital and recessive is lower case

Which of Mendel's laws is represented below?

Aa

• Law of Dominance
• Law of Segregation
• Law of Independent Assortment
• Law of Heredity

The diagram shows which of Mendel's Laws?

• Mendel's Law of Segregation
• Mendel's Law of Dominance
• Mendel's Law of Heredity
• Mendel's Law of Independent Assortment

The monohybrid Punnett square shows Mendel's Law of ​ (a)   . It does this because the ​ (b)   letter is the phenotype shown. This square also shows Mendel's law of ​ (c)   . This can be seen by testing every possible ​ (d)   combination . This is caused by fertilization being ​ (e)   , meaning we don't choose which sperm and egg make the zygote.

• dominance
• capital
• segregation
• gamete
• random
• lower case
• independent assortment

Match the following number of potential offspring with the correct phenotype from the dihybrid cross provided.

Round is dominant to wrinkled.

Yellow is dominant to green.

• 3

• green Round

• 1

• Yellow Round

• 3

• Yellow wrinkled

• 9

• green wrinkled

How do meiosis and independent assortment create genetic variation?

• Meiosis creates genetic variation through the fusion of homologous chromosomes and independent assortment during prophase I
• Meiosis and independent assortment create genetic variation by preventing the exchange of genetic material between homologous chromosomes
• Independent assortment creates genetic variation by ensuring identical alleles are passed on to offspring
• Meiosis creates genetic variation through the random assortment of homologous chromosomes and crossing over during prophase I, while independent assortment shuffles these chromosomes independently, resulting in unique combinations of alleles in the gametes.

What does the law of

independent assortment state?

• The law of segregation states that alleles of different genes segregate dependently.
• Genes located on the same chromosome always assort independently.
• Alleles of the same gene segregate independently during gamete formation.
• Alleles of different genes segregate independently during gamete formation.

Match the following gamete genotypes to the steps of the foil method. Use the crossing below:
