Answer from: Azihan

The probability of the parents having a child who is hzygous dominant for this trait is - 25%

In the given question, there is a particular character that has two alleles Y dominant allele and y recessive allele. Both parents are heterozygous for the trait that is encoded as Yy cross with Yy.

Cross between: Yy X YyIf both parents carry only one copy of a recessive gene, the likelihood of a child have the recessive trait is one in four.Offspring are produced: YY: 2Yy: yyHozygous would be represented for dominant - YYthere is one YY out of 4 offsprings

(1/4)*100

= 25%

Thus, the correct probability would be - 25%

Based on the laws of probability, the probability of the having a child who is h0m0zygous dominant for the trait indicated in the Punnet square is 25%.

What is the probability of the having a child who is h0m0zygous dominant for the trait indicated in the Punnet square?

Assuming the dominant trait is Y and the recessive trait is y.

From the Punnet square, the offspring genotype are: YY, Yy, Yy and yy.

The child having h0m0zygous dominant trait is YY.

Probability = 1/4 = 25%.

Therefore, the probability of the having a child who is h0m0zygous dominant for the trait indicated in the Punnet square is 1/4 or 25%.

Answer from: Quest

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
