Please help with just part one and punnet square
Inessa05 [86]

The earlobe trait is denoted by E and e alleles, whereas the eye trait is denoted by B and b alleles. The Punnet square allows identifying the expected proportions in the progeny.

<h3>The Punnett square and inheritance </h3>

The Punnett square is a diagram used to represent the gamete combinations in order to estimate genotypes and phenotypes in the progeny.

The earlobe trait is denoted by E and e alleles, thereby there are two types of gametes in heterozygous individuals.

In this case:

           E            e

E        EE          Ee

e       Ee          ee

Moreover, the eye trait is denoted by B and b alleles, thereby there are two types of gametes in heterozygous individuals.

In this case:

           B            b

B        BB          Bb

b       Bb          bb

bearhunter [10]

Answer:

1/16 are ovoid

Explanation:

Hello!

From an AaBb genotype we can obtain four possible gametes AB, Ab, aB and ab.  With the Punnett square we can observe the crossing.  In the second Punnett square we can see the form A– B–

AB          Ab           aB          ab

AB AABB AABb AaBB AaBb

Ab AABb AAbb AaBb Aabb

aB AaBB AaBb aaBB aaBb

ab AaBb Aabb aaBb aabb

AB          Ab          aB          ab

AB A-B-  A-B-  A-B-  A-B-

Ab A-B-  A-bb A-B-        A-bb

aB A-B-  A-B-  aaB- aaB-

ab A-B-  A-bb aaB- aabb

The genotypes of the form A– B–, A– bb and aa B– have triangular seed capsules (15 of 16), while the seed capsules of the aa bb genotypes are ovoid (1 of 16).
