Chapter 11 Flashcards
A mule is the result of a cross between a donkey and horse. A mule is a
Hybrid
A tall plant (TT) is crossed with a short plant (tt). If the tall F1 pea plants are allowed to self - pollinate
All of the offspring will be short
The principle of probability can be used to
Predict the traits of the offspring of the genetic crosses
A heterozygous tall pea plant is crossed with a short plant. The probability that an F1 plant will be tall is
50%
Organisms that have two identical alleles for a particular trait are said to be
Homozygous
What type of cells are formed from the process of Meiosis?
All of the above
If an organism’s diploid number is 12, its haploid number is
6
Gametes are produced by the process of
Meiosis
How many sex cells are functional after a male goes through meiosis?
4
Crossing-over occurs during what phase of meiosis?
Prophase 1
______________________- the process of halving chromosomes to produce sex cells
Meiosis
How many sets of chromosomes do haploid cells contain?
Half
Which is trait is dominant and which trait is recessive in the following sentence? A homozygous brown mouse is crossed with a heterozygous brown mouse.
Brown is Dominant (B)
White is recessive (b)
How many cells are produced after one cell goes through meiosis?
4
What is the difference between phenotype and genotype?
Phenotype is the physical Appearance
Genotype is genetic Make up
How many sex cells are functional after a female undergoes meiosis?
1
Two gametes, sperm and egg, combined to form a __________________________.
Zygote
