Biology ch. 6 Genetics

Produces 4 genetically different daughter cells

results in no change in the number of chromosomes

Which cells would NOT be diploid?

Spindle fibers move homologous chromosomes to opposite sides of the cell

Mendel's principles apply to human genetics.

A specific characteristic is a trait

B+ is a(n) _____________ while blood type is a(n) ______________.

Variation in skin color is due to

The study of heredity is called traits

2 cell divisions

Red and white flowers are crossed to produce pink offspring, this is an example of?

Chromosomes line up in the middle, not in homologous pairs

Produces two identical daughter cells

Diploid organisms have two sets of chromosomes.

An organism that has a genotype of Gg would be considered

Which blood type is the universal recipient?

Mendel used self-pollination during his experiments.

Dihybrid crosses look at how many genes?

Homologous chromosomes line up in the middle of the cell

What are the possible genotypes of a person with blood type O

Daughter cells are haploid

Daughter cells are diploid

Crossing over occurs and homologous chromosomes pair up

The process of joining reproductive cells is called

The nuclear membrane reforms, cytoplasm divides, 4 daughter cells are formed

What is it called when one allele is not completely dominant over the other?

The different forms of a gene are called

The separation of alleles is called

Diploid means 1 set.

What are the factors that are passed from parents to offspring?

Crossing over results in the same combination of alleles

Monohybrid crosses look at how many genes?

What happens when the phenotypes produced by both alleles are clearly expressed?

A person with genotype I^Bi would have a blood type of

1 cell division

Cytoplasm divides and two daughter cells are formed

What is the human diploid number?

When we cross a black and a white cat, we get kittens with black and white spots. This is????

Homologous means corresponding

Type AB is the "universal donor"

Who was the scientist that founded modern genetics?

If an organism has the genotype of Ff it is said to be

Results in chromosome number being cut in half

what is the diploid number of an organism with a haploid number of 44?

The process of exchanging chromatids during meiosis is called segregation

The likelihood that an event will occur.
