What genotype is not true-breeding?
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.
If a white eyed male fruit fly were crossed with a heterozygous red eyed female fruit fly what ratio of genotypes would be expected in the offspring?
In this case, the genotype of the white-eyed male fruit fly would be XwY, and the genotype of the heterozygous red-eyed female fruit fly would be XRXw. The expected ratio of genotypes in the offspring would be 1:1 for XRY (red-eyed males) and XRXw (red-eyed females).
Two heterozygous oompahs are crossed what proportion of the offspring will have orange faces?
If both oompahs are heterozygous (Oo), there are three possible genotypes that would result in offspring with orange faces: OO, Oo, and oO. Therefore, 75% of the offspring from this cross would have orange faces.
When two cultives are crossed their offspring will be?
Their offspring will be heterozygous recessive.
In flies long wings are a dominant trait and short wings are a recessive trait. If a heterozygous long-winged fly is crossed with a short-winged fly what is the LIKELIHOOD that the offspring will cont?
When a heterozygous long-winged fly (LW) is crossed with a short-winged fly (ww), the possible genotypes of the offspring are LW and ww. This results in a 50% chance of producing long-winged offspring (LW) and a 50% chance of producing short-winged offspring (ww). Therefore, there is a 50% likelihood that the offspring will have long wings.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
The possible genotypes of the offspring are Bb (heterozygous blue) and bb (white). The possible phenotypes are blue and white flowers. Each offspring will inherit one allele from each parent, resulting in a 50% chance of being blue (Bb) and 50% chance of being white (bb).
If a white eyed makes fruit fly were crossed with a heterozygous red eyed female fruit fly what ratio of genotypes would be expected in the offspring?
The cross would result in a 1:1 ratio of white-eyed to red-eyed offspring. Half of the offspring would inherit the white-eyed trait from the white-eyed male, while the other half would inherit the red-eyed trait from the heterozygous red-eyed female.
What is a useful device for predicting the possible offspring of crossed between different genotypes?
Punnet square
What will the colors of the offspring of a heterozygous yellow and green pea plant?
In pea plants, the yellow color (Y) is typically dominant over the green color (y). If a heterozygous yellow pea plant (Yy) is crossed with a green pea plant (yy), the possible genotypes of the offspring would be 50% heterozygous yellow (Yy) and 50% homozygous green (yy). Therefore, the offspring would exhibit a 50% chance of being yellow and a 50% chance of being green.
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 a hybrid tall plant is crossed with a dwarf plant then how many tall plants would be expected?
When a hybrid tall plant (Tt) is crossed with a dwarf plant (tt), the offspring can be predicted using a Punnett square. The possible genotypes for the offspring would be Tt (tall) and tt (dwarf). This results in a 1:1 ratio, meaning that approximately 50% of the offspring are expected to be tall plants (Tt) and 50% will be dwarf plants (tt).
A pansy homozygous for purple flowers is crossed with a pansy homozygous for pink flowers. Which genotypes will be exhibited in the offspring?
If the flowers are something like PP (purple) and pp (pink), then the flowers will be Pp if you do the traditional square used in most high school classes.
