Question
According to the punnett square the law of dominance, if "R" is red and "r" is white then 75% of the offspring will be red and 25% is white.
A allele Yes?
An alternate form of a gene that is located at a specific position.On a specific chromosome, we usually have 2 allies for a trait.One inherited from each parent the notion.iRR, Rr In our example is call the Gino type.When the pair of allies is identical they are called homozygous. When the pair is different they are calledheterozygous. Capital?
Letters represent dominant traits. Lower case letters, representatives. Dominant traits can mask recessive traits. The color red and white are called the phenotype.
According to Mendel's law of dominance, if we know the genotypes of the parents. With regard to a specific trait, we can use probability to determine the number of offspring displaying h trait. Use the putnet square above and the text to help you determine which three statements are true
A. HH is the genotype for the homozygous dominant condition
B. If H= hairy and h = not hairy following the law of dominance Hh would be a moderately hairy individual
C. In a field of 200 sunflowers, if 52 have orange petals and 148 have yellpw then the genotype of the parents are YY and yy
D. Given the situation a heterozygous pink pig (Pp) is crossed with a homozygous white pig (pp) all of the offspring will be pink
E. In a cross between two heterozygous pink pig (Pp) about one- fourth will be white
F. In a population of flies , red eyes or dominant over green if a homozygous red eyed fly mates with a homozygous green eyed fly the probability that they will have red eyed offspring will be 100%

Let's analyze the statements based on the principles of Mendelian genetics and the information provided:
A. **HH is the genotype for the homozygous dominant condition.**
**True.** This statement accurately describes that "HH" represents homozygous dominant, where both alleles are the same and dominant.
B. **If H = hairy and h = not hairy, following the law of dominance, Hh would be a moderately hairy individual.**
**False.** According to the law of dominance, individuals with at least one dominant allele (H) will express the dominant phenotype, which is hairy in this case. "Hh" would be hairy, not moderately hairy.
C. **In a field of 200 sunflowers, if 52 have orange petals and 148 have yellow, then the genotype of the parents are YY and yy.**
**False.** If yellow (Y) is dominant over orange (y), we would expect a 3:1 ratio of yellow to orange if the parents were heterozygous (Yy and Yy). The observed ratio (148 yellow to 52 orange) does not fit the expected Mendelian ratio for a YY x yy cross, which would yield only yellow flowers.
D. **Given the situation, a heterozygous pink pig (Pp) is crossed with a homozygous white pig (pp), all of the offspring will be pink.**
**False.** The offspring would be 50% pink (Pp) and 50% white (pp), assuming pink is dominant over white.
E. **In a cross between two heterozygous pink pigs (Pp), about one-fourth will be white.**
**True.** The Punnett square for Pp x Pp gives you a 1:2:1 ratio of genotypes (1 PP, 2 Pp, 1 pp), indicating that 1 out of 4 offspring (which is 25%) will be white (pp).
F. **In a population of flies, red eyes are dominant over green. If a homozygous red-eyed fly mates with a homozygous green-eyed fly, the probability that they will have red-eyed offspring will be 100%.**
**True.** If the homozygous red-eyed fly (RR) mates with a homozygous green-eyed fly (rr), all offspring (Rr) will have red eyes, as R (red) is dominant over r (green).
### Summary of True Statements:
- A. True
- B. False
- C. False
- D. False
- E. True
- F. True
Thus, the true statements are A, E, and F.
A. **HH is the genotype for the homozygous dominant condition.**
**True.** This statement accurately describes that "HH" represents homozygous dominant, where both alleles are the same and dominant.
B. **If H = hairy and h = not hairy, following the law of dominance, Hh would be a moderately hairy individual.**
**False.** According to the law of dominance, individuals with at least one dominant allele (H) will express the dominant phenotype, which is hairy in this case. "Hh" would be hairy, not moderately hairy.
C. **In a field of 200 sunflowers, if 52 have orange petals and 148 have yellow, then the genotype of the parents are YY and yy.**
**False.** If yellow (Y) is dominant over orange (y), we would expect a 3:1 ratio of yellow to orange if the parents were heterozygous (Yy and Yy). The observed ratio (148 yellow to 52 orange) does not fit the expected Mendelian ratio for a YY x yy cross, which would yield only yellow flowers.

**False.** The offspring would be 50% pink (Pp) and 50% white (pp), assuming pink is dominant over white.
E. **In a cross between two heterozygous pink pigs (Pp), about one-fourth will be white.**
**True.** The Punnett square for Pp x Pp gives you a 1:2:1 ratio of genotypes (1 PP, 2 Pp, 1 pp), indicating that 1 out of 4 offspring (which is 25%) will be white (pp).
F. **In a population of flies, red eyes are dominant over green. If a homozygous red-eyed fly mates with a homozygous green-eyed fly, the probability that they will have red-eyed offspring will be 100%.**
**True.** If the homozygous red-eyed fly (RR) mates with a homozygous green-eyed fly (rr), all offspring (Rr) will have red eyes, as R (red) is dominant over r (green).
