What is the chromosome number in daughter cells after meiosis if the parent cell has 60 chromosomes?

Back

30

Front

What is the relationship between gametes produced by the same individual?

What are the genotypes of heterozygous pea plant parents for round (R) and yellow (Y) traits?

What is the chromosome number in daughter cells after meiosis if the parent cell has 16 chromosomes?

Back

8

Front

What is the genotype of a carrier for an autosomal recessive disorder where the dominant allele is A and the recessive allele is a?

Back

Aa

Front

Define meiosis.

Back

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

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 is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even in the presence of a recessive allele.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present (homozygous).

Front

What is the purpose of a Punnett square?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from a genetic cross.
