True or false The contrasting forms of each character studied by Mendel appeared in a 3:1 ratio in the (F2) generation.
false, and the environment
True or false The phenotype that results from an inherited pair of alleles depends on the instructions in the genes (only).
Traits for different characters that are usually inherited together are said to be ?
Mendel used numbers to express the results of his experiments
The difference between Mendel's experiments in the area of heredity and those done by earlier researchers was that
Mendel obtained his P generation by allowing the plants to
The discovery of chromosomes provided a link between the first law of heredity that stemmed from Mendel's work and
The two alleles for a trait segregate independently during gamete formation
Mendel's law of segregation states that
Show two different phenotypes and two different genotypes
When an individual heterozygous for a trait is crossed with an individual homozygous recessive for the trait, the offspring produced will
Law of independent assortment
Mendel's finding that the inheritance of one trait had no effect on the inheritance of another became known as the
What is the expected genotypic ratio resulting from a homozygous dominant x heterozygous monohybrid cross?
What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?
Since the allele for colorblindness is located on the X chromosome, colorblindness
What would be the blood type of a person who inherited an A allele from one parent and an O allele from the other?
Genes that are close together on a single chromosome are considered to be
The dominant allele
Which allele is expressed in a heterozygous individual?
What is the term for the expression of two dominant alleles at the same time?
For each inherited trait, an individual has two copies of the gene, one from each parent.
1 Write a synopsis of the hypotheses Gregor Mendel developed based on his observations of pea plants.
There are alternative versions of genes (which Mendel called factors).
2 Write a synopsis of the hypotheses Gregor Mendel developed based on his observations of pea plants.
When two different alleles occur together, one of them may be completely expressed, while the other may have no observable effect on the organism's appearance.
3 Write a synopsis of the hypotheses Gregor Mendel developed based on his observations of pea plants.
In each parent, the alleles for each gene separate independently of one another. Thus, each parent transmits only one allele for each inherited trait.
4 Write a synopsis of the hypotheses Gregor Mendel developed based on his observations of pea plants.
