What are the cells produced by meiosis called?

Back

Sex cells/gametes.

Front

What are features that have different functions but similar structures due to a common ancestor called?

Back

Homologous structures.

Front

If the diploid number of an organism is 18, what is the haploid number?

Back

9.

Front

In a genetic cross, if a male rabbit with genotype GGbb is crossed with a female rabbit with genotype ggBb, how many out of 16 offspring will have grey fur and black eyes?

Back

8.

Front

What is the result of crossing-over during meiosis?

Back

New combinations of genes on each chromosome.

Front

Define meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing four haploid cells from one diploid cell.

Front

What is a gamete?

Back

A gamete is a sex cell (sperm or egg) that carries half the genetic information of an organism.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes (2n), while haploid cells have one set of chromosomes (n).

Front

What are vestigial structures?

Back

Vestigial structures are remnants of organs or structures that had a function in an early ancestor but are no longer functional in the current organism.

Front

What is genetic variation?

Back

Genetic variation refers to the diversity in gene frequencies within a population, which can result from mutations, gene flow, and sexual reproduction.
