Question

How to determine a dominant trait in allele​

Answer 1

Answer:

When a trait is dominant, only one allele is required for the trait to be observed. A dominant allele will mask a recessive allele, if present. A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa..........☺

Answer 2

to check dominant trait you can use test cross means cross the dominant parent with recesive trait

if all the f1 generation are same then it means trait is dominant and if come in 50:50 that means it is heterseregs dominant
