INHERITANCE GENETICS

An earthworm has 36 chromosomes in diploid cells. what is the gamete number?

• 12

• 18

• 24

• 36

What fact is true about meiosis?

• same number of chromosome as parent

• two cell division, four daughter cells

• daughter cell identical to parent

• associated with growth & asexual reproduction

Which statement about meiosis is true?

• 2 identical cells, diploid

• 2 different cells, different

• 4 identical cells, haploid

• 4 different cells, haploid

During Meiosis, crossing over usually occurs. why is this important?

• decreases genetic variation

• increases genetic variation

• changes chromosome number

• changes number of genes in cell

Which statement is correct about the two cell division processes?

• meiosis and mitosis both occurs in all types of cells

• both produce cells with the same numbers of chromosome

• chromosome number half in meiosis, same in mitosis

• cell matter equal in meiosis, unequal in mitosis

Which statement is true about mitosis & Meiosis?

• daughter cells formed by meiosis & mitosis similar to parent

• daughter cell formed by mitosis & meiosis different from parent

• mitosis- asexual reproduction;

  Meiosis- sexual reproduction

• mitosis- sexual; meiosis-asexual

White flowers cross with red flowers, pink off-springs. What's the inheritance pattern?

• codominance

• complete dominance

• incomplete dominance

• multiple allele

A cross between 2 flowers, B is for blue, & b is for white flowers. what genotype represent white-flowered offsprings?

• bb

• Bb

• Bb and bb

• BB and Bb

brown fur (B) is dominant over white fur (b). A cross between Heterozygous brown with a white. what the percentage of white off-springs?

• 100% BB

• 25% BB, 25% bb, & 50% Bb

• 50% Bb and 50% bb

• 75%BB and 25% Bb

What relationship exists between A and B alleles for blood grouping?

• codominance

• complete dominance

• incomplete dominance

• sex linked
