he Punnett square shows the cross for a particular trait between a homozygous dominant parent and a heterozygous parent. What is
Crazy boy [7]

Answer:

50%

Explanation:

Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.

One homozygous dominant parent = XX

One heterozygous parent = Xx

      X    X

X   XX  XX  

x    Xx  Xx

So two out of our four outcomes are heterozygous for the trait. That means the answer is <u>B. 50%.</u>

Albinoism is an autosomal recessive trait. What is the probability of two
FinnZ [79.3K]

Answer:

1. Probability is 50% or 1/2

2. a) Genotypic ratio= 1 AA: 2Aa : 1aa

   b) Phenotypic ratio = 3 normal pigment : 1 albino

3. Monohybrid cross

Explanation:

This question involves a single gene coding for pigment in humans. The allele for normal pigmentation (A) is dominant over the allele for albinism (a).  

According to this question, if two heterozygous parents (Aa) are crossed i.e. Aa × Aa. The following proportion of offsprings will be produced:

AA, Aa, Aa, and aa

- Hence, the probability of having a heterozygous offspring is 2/4 or 1/2 or 50%

- Genotypic ratio= 1 AA: 2Aa : 1aa

  Phenotypic ratio = 3 normal pigment : 1 albino

c. This type of cross is called MONOHYBRID CROSS because it involves a single gene
