In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
What percent of the offspring will be short around?
60%
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
How was Mendel able to determine that certain traits were dominant and some were recessive?
Mendel crossed pea plants with contrasting traits and observed the offspring. He found that one trait (dominant) masked the expression of the other (recessive) in the first generation. By allowing the plants to self-fertilize over multiple generations, he determined the patterns of inheritance and identified the ratios of dominant to recessive traits in the offspring.
If a female fruit fly heterozygous for red eyes XRXr crossed with a white eyed male XrY what percent of their offspring would have white eyes?
50% of the offspring would have white eyes. This is because all females from the cross would inherit the Xr from the male, resulting in red-eyed females, while males would inherit the Xr from the female fruit fly, resulting in white-eyed males.
What percent chance of having offspring having white hair when a purebred black rabbit is crossed with a hybrid black rabbit?
50%
If a test cross between a homozygous recessive and heterozygous allele will yield what percent of offspring as homozygous recessive?
A test cross between a homozygous recessive and a heterozygous individual will yield 50% of offspring as homozygous recessive. This is because all the offspring will inherit one recessive allele from the homozygous recessive parent.
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.
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
What offspring is produced if a heterozygous n tall pea plant is crossed with a homozygousfor this trait what percent of the offspring will be heterozygous?
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
If tall peas are crossed with dwarf peas what percent of the peas will be tall in the first generation?
In the first generation of crossing tall peas with dwarf peas, all the offspring will be tall. This is because the tall trait is dominant over the dwarf trait. Each offspring will inherit one tall allele from the tall parent, resulting in all tall offspring.
What percent of the offspring will be short round?
good stuff
A mother that is heterozygous for a trait and a father who is homozygous recessive for the same trait have offspring Use this information to complete the matching below Enter the letter of the item?
A. Offspring with heterozygous genotype 100 percent B. Offspring with homozygous dominant genotype 0 percent C. Offspring with at least one copy of recessive gene 50 percent
A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
If a female fruit fly heterozygous for red eyes crossed with a white eyed male what percent of their offspring would have white eyes?
All the offspring will have red eyes because the trait for red eyes is dominant and the female is heterozygous (carrying one dominant red eye allele). White eyes are recessive, so the offspring would need to inherit two white eye alleles to have white eyes.
What is the approximate probably that human offspring will be female?
50 percent
A cross between a white rooster and a black hen is 100 percent blue offspring when two of these offspring are mated the probable phenotypic ratio seen in their off spring would be what?
If you crossed a black hen/roo with a white hen/roo, the offspring would NOT be blue. If he was recessive white, the chicks would be black. If he was dominant white, the chicks would be white with some black "smudges" or "spots". The only way to produce 100% blue chicks is to cross a black roo over splash hens or a splash rooster over black hens.
