Answer:
Given that;
A = big apples; a = small apples;
R = red apples; r = yellow apples.
The genotypes of the parents are;
AArr and aaRr
Explanation:
When the trees are crossed, Trees that produce big yellow apples could be AArr or Aarr while trees that produce small red apples could be aaRR or aaRr.
The big parent must be homozygous for A, because all the offspring are big.
The red parent must be heterozygous for red, because half the apples are red and half are yellow.
Therefore, the cross must be AArr and aaRr.
Answer:
the genotype for the parent trees are:
AArr (big, yellow apples) and aaRr (small, red apples)
Explanation:
Only a dihybrid cross of the following parent genotypes will give a probability of 50% for each phenotype, that is - big, red apples and big, yellow apples.
The genotype of the offspring is the following:
Big, red apples: AaRr
Big, yellow apples: Aarr
Here, the trait 'big' is dominant over 'small' and the color 'red' is dominant over 'yellow', as represented by the alleles given in the problem statement.
Hope that answers the question, have a great day!
