Genotype of Rhode Island red variety of poultry bird is denoted as RR and that of White leghorn as rr. When these two are crossed - What variety of bird would you expect in their F1 progeny
- Give the percentage of White Leghorn, if F1 birds are doing natural insemination.
- In what ratio would you find the genotypes RR and Rr in F2 progeny.
1) In the F1 generation all hybrids will have red colour as it is dominant while white is the recessive one. All hybrids will have the genotype Rr.
2) 25% of the F2 generation will be White Leghorns.
3) Ratio of RR and Rr will be 1;2 in the F2 progeny.
2) 25% of the F2 generation will be White Leghorns.
3) Ratio of RR and Rr will be 1;2 in the F2 progeny.
