Question

1. circle all choices that match the word.

(1) heterozygous nn, aa, bb, hh, yy, yy, aa, gg, oo, ee
(2) homozygous dominant bb, aa, ee, nn, hh, hh, aa, ll, mm, gg
(3) homozygous recessive yy, gg, aa, bb, nn, nn, ll, oo, ee, aa
(4) recessive allele a, n, k, b, h, m, n, j, y, y

Explanation:

1. Heterozygous genotypes have one dominant and one recessive allele (different letter cases).
2. Homozygous dominant genotypes have two identical dominant (uppercase) alleles.
3. Homozygous recessive genotypes have two identical recessive (lowercase) alleles.
4. Recessive alleles are represented by lowercase letters.

Answer:

(1) Heterozygous: Nn, Bb, Yy, Aa, Gg
(2) Homozygous dominant: AA, NN, LL, MM
(3) Homozygous recessive: aa, hh, oo, ee, nn
(4) Recessive allele: a, b, n, j, y
