Question
In a newly discovered diploid organism called Aggiesrus, fur color is controlled by the Y gene with Y = yellow fur and y = white fur. Another gene, T controls tail length with T = long tail and t = short tail. If a yellow-fur, long tail male is crossed to a white-fur, short tail female all the F1 have yellow fur and long tails. What are the parent and progeny genotypes based on only the information given in this question? (assume all parents are true breeding) P: YYtt male x yyTT female F1: YYTT P: YYtt male x yyTT female F1: YyTt P: YYTT male x yytt female F1: YyTt P: yyTT male x YYtt female F1: YyTt P: YyTt male x YyTt female F1: YyTtExplanation / Answer
Answer
the correct options are
2. YYtt Male x yyTT female F1 Progeny YyTt
3. YYTT Male x yytt female F1 Progeny YyTt
4. yyTT Male x YYtt female F1 Progeny YyTt
All the F1 offsprings are hybribds with Yellow fur and Long tail, because yellow and long taliled charecter is dominanat trait
The cross where at a time two pairs of contrasting characters had been considered are known as dihybrid
crosses.Mendel formulated Law of independent assortment on the basis of this cross
A true-breeding organism is one that, when self-fertilized, only produces offspring with the same traits. They are genetically identical and have identical alleles for specified traits. The alleles are homozygous. A true-breeding plant with round seeds will have a genotype of (RR) and a true-breeding plant with wrinkled seeds will have a genotype of (rr).
