The many names of chromosomes
Alleles, genotypes, and types of crosses
Different modes of inheritance
100
One of the two phases of cell cycle: PREPARATION for cell division.
What is INTERPHASE
100
The FIRST STAGE of mitosis
What is PROPHASE
100
The 'USABLE' FORM of DNA. Present during INTERPHASE.
What is DECONDENSED DNA.
100
This TYPE OF ALLELE masks the other allele.
What is DOMINANT ALLELE
100
In this TYPE OF DOMINANCE, when A TRUE-BREEDING WHITE sheep is crossed with a TRUE-BREEDING BLACK sheep, all their offspring come out GRAY.
What is INCOMPLETE DOMINANCE. (Dominant allele wins ______________, so a heterozygote is "IN-BETWEEN" the parents.)
200
Division of CYTOPLASM
What is CYTOKINESIS
200
The STAGE OF MITOSIS in which chromosomes ALIGN IN THE MIDDLE
What is METAPHASE
200
The 'MOVABLE' or CONDENSED FORM of DNA is present only during THIS PHASE of cell cycle.
What is MITOSIS
200
A COMBINATION OF ALLELES responsible for what we see. (Two alleles for every gene.)
What is a GENOTYPE.
200
In this TYPE OF DOMINANCE, when A TRUE-BREEDING WHITE sheep is crossed with a TRUE-BREEDING BLACK sheep, all their offspring come out WHITE.
What is COMPLETE DOMINANCE. (Dominant allele wins _________________, so a heterozygote looks like one of the parents.)
300
Division of DNA/CHROMOSOMES/NUCLEUS
What is MITOSIS
300
In this STAGE OF MITOSIS, chromosomes ARRIVE, nuclear envelope REAPPEARS, and spindle DISAPPEARS
What is TELOPHASE
300
A chromosome made of TWO SISTER CHROMATIDS linked together by a CENTROMERE
What is a DUPLICATED CHROMOSOME
300
In this genotype, the two alleles are DIFFERENT. It is also known as HYBRID.
What is HETEROZYGOUS
300
In this TYPE OF DOMINANCE, when A TRUE-BREEDING WHITE sheep is crossed with a TRUE-BREEDING BLACK sheep, all their offspring come out CHECKER-BOARD (some black and some white patches).
What is CO-DOMINANCE. (Both alleles win/we see BOTH black and white.)
400
The second phase of cell cycle: consists of MITOSIS and CYTOKINESIS
What is MITOTIC PHASE
400
In this STAGE OF MITOSIS, sister chromatids become NEW CHROMOSOMES.
What is ANAPHASE. (Recall that sister chromatids change their name to "new chromosomes" once they separate.)
400
What we call SISTER CHROMATIDS after they separate.
What is NEW CHROMOSOMES
400
Dd Hh x Dd Hh is an example of this TYPE OF CROSS
What is a DIHYBRID CROSS
400
In this MODE OF INHERITANCE, a gene has 5 alleles.
What is MULTIPLE ALLELES (Anything more than _____ per gene is considered multiple alleles.)
500
The PHASE OF INTERPHASE in which the cell carries out DNA SYNTHESIS (aka DNA replication)
What is S PHASE (S is for _________________.)
500
In this STAGE OF MITOSIS, individual chromosomes BECOME VISIBLE. (The nucleus starts looking like a speckled egg.)
What is PROPHASE.
500
This pair of chromosomes has the same genes but different alleles.
What is HOMOLOGOUS CHROMOSOMES
500
This TYPE OF CROSS is done to figure out whether someone with dominant phenotype (e.g., a white sheep) is really homozygous dominant (WW) or heterozygous (Ww).
What is a TEST CROSS
500
In this MODE OF INHERITANCE, an inherited feature is controlled by 2 genes. (The effects of the genes are ADDITIVE.)
What is POLYGENIC INHERITANCE. (Anything more than _____ genes per inherited feature is considered polygenic.)
