Which punnett square shows the result of a cross between two heterozygous parents?
A cross between two heterozygous parents (eg. Gg X Gg) would result in a phenotypic ratio of 3 dominant : 1 recessive, and a genotypic ratio of 1GG:2Gg:1gg.GgGGGGggGggg
What term describes the parents in monohybrid cross?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
What are the genotype a of the parents?
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.

What will happen when a Heterozygous with dominant phenotype self fertilizes?
Heterozygous dominant.D = dominantd = recessiveSame as out breeding for cross with other heterozygous dominant.Dd X DdDDDdDddd
What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?
Scientists use a test cross to determine if an organism is heterozygous or homozygous dominant.
What term describes the parents in a mono-hybrid cross?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
A cross that considers one pair of contrasting traits?
A dihybrid cross is the cross that involves parents that differ in two traits.
Which punnett square shows the result of a cross between two heterozygous parents?
A cross between two heterozygous parents (eg. Gg X Gg) would result in a phenotypic ratio of 3 dominant : 1 recessive, and a genotypic ratio of 1GG:2Gg:1gg.GgGGGGggGggg
What term describes the parents in monohybrid cross?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
What is the offspring of two parents from different purebred strains?
By the process of hybridization, breeders cross two genetically different organisms. The purpose is to have the best traits of both parents.
Why does the cross between two parents that are homozygous for contrasting traits result in offspring that are heterozygous?
They R pretty wierd!
What are the genotype a of the parents?

What generation is always completely heterozygous?
The F1 (first filial) generation is always 100% heterozygous.This is because the F1 generation is defined as the offspring of pure-breeding (homozygous) parents carrying different alleles from each other, e.g. AA x aa. All the offspring must be Aa, in other words heterozygous.
Which type of cross would produce 100 percent heterozygous offspring?
A cross between two homozygous parents will form a 100 percent chance of a heterozygous offspring. One homozygous parent must have the dominant allele, and the other must have the recessive allele. So, if the circumstances are correct, these characteristics will make for a 100 percent chance of a heterozygous offspring.
What is the expected genotypic ratio for a one factor cross of two hybrid organisms?
1 homozygous dominant: 2 heterozygous: 1 homozygous recessive
What cross between parents will result in an approximate 3 to 1 ratio?
A monohybrid cross is a cross between parents who are heterozygous at one locus; ... The results The wrinkled trait --- which had disappeared in his hybrid ...of them produced both types of seeds in the F3 and - once again - in a 3:1 ratio
What term describes the parents in a mono-hybrid?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
