A hybrid organism is the offspring of many generations that have the same form of a trait.
Capital letters are used to represent recessive alleles.
Mendel called an individual that has one dominant allele and one recessive allele for a trait a purebred.
Mendel said that the factors that control a trait exist in pairs
Body cells of humans have 46 pairs of chromosomes.
Sex cells have twice the number of chromosomes as body cells.
Genes pass from parents to offspring on chromosomes.
The two chromosomes in a pair have the same genes lined up in the same order.
What Mendel called factors are now called
When parent plants are crossed, scientists refer to the first generation of offspring as
The allele for a hybrid tall pea plant is represented as
Which of these is NOT a phenotype?
genotype is heterozygous.
The physical appearance of an organism is its
A Punnett square shows the combination of DNA genes alleles that parents can pass on to offspring.
The genetic makeup of an organism is its
If a plant with red flowers crossed with a plant with white flowers produces a plant with pink flowers, it is an example of dominance.
Four alleles determine if a rabbit is white, brown, or gray. This is an example of alleles.
A cow with a mix of red hairs and white hairs has the genotype HRHW. This is an example of .
The pattern of inheritance in which one allele is only partially dominant is
The process that produces sex cells is .
In the division of meiosis, chromosome pairs line up and then separate.
In the division of meiosis, chromosomes split.
