Genetics and Meiosis

Three cells that each has a diploid number of 32 go through meiosis. How many cells result and how many total chromosomes are in each cells?

• 14 cells with 32 chromosomes

• 12 cells with 32 chromosomes

• 12 cells with 16 chromosomes

• 9 cells with 4 chromosomes

Meiosis in female human cells results in

• 2 oocytes

• 2 spermatocytes

• 1 oocyte and 3 polar bodies

• 4 oocytes

Gametes have to be haploid because

• when they fuse, they will form a haploid zygote

• when they fuse, each gamete contributes 46 chromosomes

• when they fuse, each haploid gamete makes a diploid zygote

• upon fusing at fertilization, the resulting zygote will have half of the whole.

The outward expression of a gene

• genotype

• phenotype

• dominance

• codominance

An alleles that will not determine the phenotype unless the genotype is homozygous for that allele

• dominant

• recessive

• codominant

• incomplete dominant

The letters that represent the alleles an organism possesses for a certain trait

• dominant

• genotype

• phenotype

• allele frequency

A cross between two individuals focusing on two traits

• monohybrid

• punnett cross

• dihybrid

• pedigree

A plant or animal that has been genetically altered by people

• genetically modified organism

• transgenic organism

• plasmid

• incomplete dominant

Pink flower color is often the result of which of these

• codominance

• incomplete dominance

• genetic recessiveness

• multiple alleles

During gamete formation, genes for different traits separate without influencing each other's inheritance is known as what genetic law?

• Law of segregation

• Law of dominance and recessiveness

• Law of independent assortment

• Law of probabilities
