Question

1. In pea plants, Round seeds are dominant (R) and wrinkled seed are recessive (r). a. What would the parent look like(phenotype) if its genotype is RR? What is the name of this type of genotype? Use genetic terms you learned. b. What would the parent phenotype be is it was Rr? What is the name of this type of genotype? c. What would the parent genotype be if it was wrinkled? What is that called? d. If you crossed a RR x rr what would the genotype and phenotype be of the offspring? Use a Punnett square to explain the probability of each color. e. What would the offspring look like if you crossed heterozygous round pea plant with a homozygous wrinkled pea plant? Use a Punnett square to explain the probability of each color.

Please show the punnett squares where needed. Need this done ASAP thx.

Answer 1

Answere: Here, Round seeds are dominant CR). and urninkled seeds ace recessive cre). → of the ? genotype of e parent iš RR. like Cphenotype) → ROUND. then, the parent will look This type of genotype is called Homozygous Dominant. * (b) of it was Rre, the parent phenotype would have been ROUND (Because, R is dominant). This type of genotype is called Heterosygous Dominant artunklede was the would parent have → (c), 94 it genotype been rere is called This type of genotype → homozygous recessive we cross a RR X IC → (a)p. Of re re R Rre Rre R Rre Rre. have All the offepning will And their phenotype would genotypes Rre be → ROUND

(e) Of we CROSS a heterozygous round pea plant with a etuin kled pea plant, somogy gous Heterogy gous round oy gous pea plant → Rre Homo wrein kled pea plant Ich. R r Rr mere T Rr ruri. Herre, out of Round offsprong A, numbere of offspre Round 2 (Two). [Rec] out of 4, number of wrinkled offspring 2 (Two) [ren] .. Probability of R 24 = 'a =50%. Round Offspring coninkled offspring Probability of coru'n kled 44=% = 50%

2. arte dominant (7) and Greeen peas arte of yellow peas recessive cy). Then, genotype of a green green pea → 99. 8. Possible genotypes of yellow peas . arce 0 УУ Homozygous Dominant) 2 yy (Heterozygous Dominant). 94 is because, y is dominant oven ५. 4. Cross bet aleen pea heterozygous yellow pea plant and greeen plant: Genotype ਥੋਂ ? Heterozygous yellow pea plant :- Yy 'Green pea plant Q у g y Yy 44 y Yy 2 Offspringe - Y y Cyellow pea plant) egy (green pea plant). Bo, Probability of getting green peas → 2/4 % - 50%
