A monohybrid cross is a cross between two individuals with different alleles at one genetic locus. If we cross two heterozygous individuals (Aa), then the percentage of offsprings with recessive phenotype will be: Aa x Aa = AA Aa Aa aa, so recessive phenotypes would be 1/4 = 25%. Thus, the correct answer is option D.
A purebred organism is the offspring of two homozygous parents. A hybrid on the other hand, comes from two heterozygous parents, which is a cross between two species. Which type of cross would produce 100 percent heterozygous offspring?
Do a punett square (Bb= heterozygous) B b B b 2. The outcomes would be BB, Bb, Bb, and bb 3. Your answer would be 50% since there are 2 that are heterozygous and 4 total outcomes. 2/4=1/2=50%
What Crosses Will Produce Heterozygous Offspring? A cross between two different true-breeding individuals will produce heterozygous offspring. In genetics, the suffix “-zygous” refers to the allele pair an organism has for any given gene.

What happens when both parents are heterozygous?
If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widow’s peak (see figure). A Punnett square can be used to determine all possible genotypic combinations in the parents. A pedigree that depicts a dominantly inherited trait has a few key distinctions.
When you cross two heterozygotes the offspring will most likely be?
In a cross between two heterozygotes (Aa), the next generation will be in the ratio 1:1 homozygotes (AA, aa) to heterozygotes (2 Aa).)
What produces a heterozygous offspring?
Kinds of Genetic Crosses This is because when the heterozygous parent produces gametes, half carry the dominant allele and half carry the recessive allele. In genetics, this kind of cross is called a test cross for historical reasons.
What is the probability of two heterozygous parents having a heterozygous offspring?
The chance of either parent being a heterozygote is 1/4, as calculated above. Then, the probability that both parents are heterozygotes, and the probability that two heterozygotes will have a heterozygous child, is 1/4 x 1/4 x 1/2 = 1/32.
What is an AA in genetics?
The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
What offspring would you expect from parents that are AA and AA?
Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
Is AA heterozygous recessive or dominant?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
Is AA homozygous dominant or heterozygous?
Homozygous and Heterozygous If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous. Keep in mind that an organism can’t simply be ’homozygous,’ period.

They each do fine, but they can interbreed and produce offspring that have intermediate beaks — too thick to reach the fine seeds that one parent eats, but too delicate to crush the nuts that the other parent eats. Those intermediate offspring will die off, and both parents will have wasted their resources raising them.
