answer to the homework question
i) 4/4 or 4 out of 4 of the individuals are with yellow seed and inflated pod
ii) 0 because of absence of ii gamete
iii) 0 because of absence of yy gamete
iv) 1/4 or 1 out of 4 ( YYII = 1 and other combinations are not possible as per question)
thankyou so much ma'am for today's session❤❤
My answer is correct ☺️
Can u explain the first one?
Hi
@@vanshikachouhan6836 Firstly here the cross of each character : seed color (YY x Yy) and pod shape (II x Ii) is done to get individual ratios.
YY x Yy crossing will give 4 combinations (YY, YY, Yy, Yy) and same for II x Ii cross (II, II, Ii, Ii)
As of here, the talk is about phenotype, so we are calculating the phenotypic ratios differently.
For Seed color, all are yellow, So phenotypic ratio comes to 1.
Same for pod shape, all are inflated so the phenotypic ratio of pod shape is 1.
Question is about individual having yellow seed and inflated pod so
Phenotypic ratio = 1 × 1 = 1
We can write 1 as 4/4 (specifically 4 because number of offspring is 4)
That's it

Ist one answer?
Ans of a would be 0??
TODAY,S HOMEWORK SOLUTIONS::
a) 4/16 ( 4 out of 16 individuals have yellow seed and inflated pod)
b) Yy ii. : 1/2 × 0 = 0 individuals
C) yy II :. No progeny was obtained with this genotype.). So answer is 0
d) possibilities were:
1) YY II : 1/2 × 1/2 = 1
2) YY ii : 0 ( 1/2× 0= 0)
3) yy ii : 0 ( no progeny was obtained with this genotype)
4) yy II : 1/2×0= 0
SO Answer of d) : 1
