Answer:
According to the information, the parent red tulip plants have a heterozygous genotype for red colour. The allele for red colour is dominant whereas the allele for white colour is recessive. Hence, the recessive allele will be masked by the dominant allele and the parent plants will have red tulips.
When heterozygous red tulip plants will be crossed, then 25% red homozygous plants will be made, 50 % would be red heterozygous plants whereas 25% would be white homozygous.
Answer: Dominant: red, recessive: white.
Explanation:
Alleles are different forms or versions of a gene, and they can be described as either dominant or recessive.
Dominant traits are those that are seen in a heterozygous genotype. It means the organisms has two different alleles for a gene, one is dominant while the other one is recessive. A dominant allle dominates over the recessive alleles and it masks the effects of this recessive allele. This means, the offspring only needs to inherit one dominant allele to have a dominant trait.
In the example, a red-flowered plant is crossed with a white-flowered plant. And all plants on the next generation are red. If each plant from this offspring inherites one allele of each parent, they have one red allele and one white allele. Since they are all red, we can say red color is dominant and white color is recessive. Because red allele has a dominant phenotype.
