Meiosis and Mendelian Genetics Review

Front

What does a dominant trait do in genetics?

Back

It masks the other trait and shows if present.

What are structures that are similar in size, shape, and genetic content, but may carry different versions of the same genes?

Back

During which process are haploid cells formed?

Back

Meiosis.

Front

What is the definition of meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells.

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles.

Front

What is an allele?

Back

An allele is a variant form of a gene that can produce different traits.

What is the law of segregation?

Back

The law of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.
