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 determines whether an organism is heterozygous or homozygous dominant?
The second allele. If a plant is heterozygous tall, it is Tt. In this case, the dominant trait is tall, T and recessive is short, t. There are two options for it to be dominant, heterozygous (Tt) or homozygous (TT)
What is crossing a homozygous dominant or homozygous recessive with a heterozygous?
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
How do two heterozygous organisms produce on offspring with a recessive phenotype?
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.
Which is the dominant gene father has dark brown eyes mother has blue eyes?
Sure you don't mean heterozygous dominant? If you don't there would be no blue eyed offspring. Let's assume you meant heterozygous dominant.B = brownbl = blueBbl X Bbl1/4 of the offspring would have blue eyes, 25%.
If purple flower color is dominant over white flower color how can two purple flowered parents produce while flowered offspring?
It can happen when both parents are a heterozygous
What is the difference between purebred organism and a hybrid?
A purebred organism is the offspring of two homozygous parents, having either two dominant alleles, AA or two recessive alleles, aa. A hybrid is the offspring of two heterozygous parents, Aa.
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 is an example of two heterozygous parents?
The possible genotypes of parents who are heterozygous would be found using a punnet square. The outcome would be 50 percent heterozygous dominant, 25 percent homozygous dominant, and 25 percent homozygous recessive.
If purple flower color is dominant over white flower color how can two purple flowered parents produce white flowering offspring?
It can happen when both parents are a heterozygous
If purple flower color is dominant over white flowers color how can two purple flowered parents produce white flowered offspring?
It can happen when both parents are a heterozygous
What is when an individual has two copies of a dominant allele?
The person is considered to be heterozygous dominant. Heterozygous refers to having to of the same allele (AA or AA). dominant means AA not AA
What determines whether an organism is heterozygous or homozygous dominant?
The second allele. If a plant is heterozygous tall, it is Tt. In this case, the dominant trait is tall, T and recessive is short, t. There are two options for it to be dominant, heterozygous (Tt) or homozygous (TT)
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 is the opposite of homozygous of dominant?
heterozygous recessive
What is crossing a homozygous dominant or homozygous recessive with a heterozygous?
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
In incomplete dominance genotypes can be expected to appear in a ratio of?
The expected phenotype for a Mendal F1 monohybrid cross is 3:1. Looking at heterozygous parents (F1) who share the same dominant trait, e.g. Straight tail.Crossing two heterozygous parents from the F1 generation results in an F2 generation that produces a 75% chance for the appearance of the dominant phenotype, of which two-thirds are heterozygous, and a 25% chance for the appearance of the recessive phenotype, giving the ratio 3;1.Inheritance pattern of dominant and recessive phenotypes when each parent is homozygous for either the dominant or recessive trait. All members of the F1generation are heterozygous and share the same dominant phenotype, while the F2generation exhibits a 3:1 ratio of dominant to recessive phenotypes.
