Mendel Genetics

What does heterozygous mean?

• Having two identical alleles for a specific gene, such as 'MM'.

• Having two different alleles for a specific gene, such as 'Mm'.

• Having one allele for a gene and no allele for another gene.

• Having three different alleles for a specific gene.

What is Mendel's Law of Independent Assortment?

• Mendel's Law of Independent Assortment states that alleles for different traits are distributed to gametes independently of one another.

• Mendel's Law of Independent Assortment states that alleles for the same trait are inherited together.

• Mendel's Law of Independent Assortment states that traits are inherited in a fixed ratio.

• Mendel's Law of Independent Assortment states that dominant traits always mask recessive traits.

What does it mean if a trait is expressed?

• It means that the phenotype associated with that trait is visible in the organism.

• It indicates that the trait is recessive and not visible.

• It suggests that the trait is only present in the genotype.

• It means that the trait has no effect on the organism's appearance.

The pollen grain contains the ...

• sperm or male sex cell

• egg or female sex cell

• chlorophyll for photosynthesis

• starch for energy storage

What is the dominant trait in pea plants?

• Tall plants (HH, Hh)

• Short plants (hh)

• Green seeds (GG, Gg)

• Yellow seeds (gg)

Law of Independent Assortment

• States that genes of different traits can segregate independently during gamete formation

• States that all genes are inherited together

• States that traits are inherited in a fixed ratio

• States that dominant traits always mask recessive traits

What organism did Mendel study?

• Pea plants

• Fruit flies

• Mice

• Wheat

What is a cross in genetics?

• A type of genetic mutation

• The mating of two organisms to study the inheritance of traits

• A method for cloning organisms

• A technique for gene editing

Pure bred

• Same 2 alleles-hh or HH

• Different alleles such as Hh

• Only one allele present

• Alleles are mixed and varied

What is a trait?

• A trait is a specific characteristic of an organism, such as flower color or seed shape.

• A trait is a type of habitat where organisms live.

• A trait is a method of reproduction in plants.

• A trait is a classification of organisms based on their diet.
