Asexual reproduction produces _____________________.

A gamete is ________________________.

An image of the chromosome pairs of a cell is called a ___________________________.

A _______________ cell would be produced by meiosis.

A karyotype is _______________________.

Which step happens in both mitosis and meiosis?

Movement of the chromosomes during anaphase would be most affected by a drug that prevents which of the following processes?

A cell in G2 of the cell division cycle contains 20 chromatids. How many centromeres are present in this cell?

If a sexually reproducing organism has a diploid number of 36, how many individual chromosomes would any of its gametes have?

An organism's _____________________ describes its genetic makeup, specifically the alleles the organism has for a particular gene or genes.

A woman has type A blood, a man has type B blood, and their child has type O blood. What is the woman's genotype?

Which term describes the ability of a single gene to have multiple phenotypic effects?

The human disease sickle-cell anemia is caused by inheriting two copies of a mutant allele for one of the hemoglobin proteins. Carriers who have one copy of this allele are more resistant to malaria, an infectious disease transmitted by mosquitoes. If two heterozygous parents (Aa) have a child, what is the chance that the child will be heterozygous and resistant to malaria?

Patients with Huntington disease have one copy of a dominant disease allele (Hh). If two parents with genotypes Hh and hh have a child, what is the chance that the child will have genotype Hh and develop Huntington disease later in life?

In cats, black fur color is caused by an X-linked allele (Xb); the other allele possible at this locus causes orange fur color (XB). The female heterozygote (XBXb) is tortoiseshell (a mix of black and orange fur colors). What offspring would you expect from the cross of a black female (XbXb) and an orange male (XBY)? 

If a new disease or environmental condition affects a population, only the individuals with favorable allele combinations will survive. If all individuals had the same alleles, the species might become extinct. Meiosis, including the processes of crossing over and independent assortment, produces gametes with significant ________________, which enhances survival.

If an embryo has the karyotype 45, X, this would be an example of ______________________.
