What is a breeding experiment where a single trait controlled by two alleles is examined called?
monohybrid cross
What oranism has two different alleles for a trait?
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
What does co-dominance mean in genetics?
Codominance is when neither trait is dominant nor recessive. Both traits are equally likely to occur and the offspring is often from a blending trait. For example, if two co dominant animals mate and one is brown and the other is white, the offspring will be a blending of both colors.
What are the two types of selective breeding?
There are more than two, but two of them can be Monohybrid Cross (a cross involving one trait/gene from a single locus, and Dihybrid Cross (a cross involving 2 traits/genes occupying two different loci
What has two identical alleles for a trait?
A heterozygote is an organism with two different alleles for a trait.
What is a breeding experiment where a single trait controlled by two alleles is examined called?
monohybrid cross
What did mendel find in the f1 generation?
he crossed two pure lines
How does a monohybrid differ from a dihybrid with respect to allele pairs?
monohybrid is a cross between two heterozygous (Aa x Aa), they are usually controlled by different alleles of the same gene. A monohybrid cross compares only one trait. while Dihybrid is a cross between F1 offsprings of two individuals that differ in two traits. Dihybrid croos are often used to test for dominant and recessive genes in two separate characteristics.
What is the difference between a monohybrid and dihybird cross?
monohybrid cross deals with one genotypic trait whereas the dihybrid cross deals with two traits being crossed to see the possible genotypes.
What is momohybrid cross?
Mono means "one" and the two parent plants differ from one another by single trait-height.
What is a momohybrid cross?
Mono means "one" and the two parent plants differ from one another by single trait-height.
Albinism or the lack of color is a recessive trait that is present in some plants Cross two carriers for albinism If 500 plants resulted from the cross what percent of offspring would be expected?
25%
What is an organism with two genes for a trait called?
An organism with two like alleles for a trait is homozygous for that trait.
What is a plant with two dominant or two recessive alleles said to be?
Heterozygous alleles are used to describe the 'parents' when creating a test cross chart. When completing a test cross there is more than comparing alleles, you are really comparing genetics. Heterozygous YY or yy versus Homozygous Yy, is just the first to consider.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
How many traits are examined in a monohybrid cross?
"Mono"- One. One trait from each parent In a Dihybrid Cross it's two traits from each parent.
