A plant with round seeds is crossed with a plant with wrinkled seeds. Draw a Punnett square to predict the outcome
of this cross. List the possible genotypes and their phenotypes. You may need to draw more than one punnet
square. (Note: Round is dominant to wrinkled)

Explanation:

A cross between plants with round seeds (RR) and plants with wrinkled seeds (rr).  If both parents are homozygous, having one type of gamete each, i.e. R from round seed parent and r from wrinkled seed parent (RR X rr).

    R     R

r   Rr     Rr

r   Rr     Rr

All the offspring of generation would be round with genetic constitution Rr. They will be heterozygous plants having two different alleles.  

If both parents has heterozygous round seeds with genotype Rr. So, we have Rr × Rr. The gametes produced from each of the parents are of two types, R and r.

     R      r

R    RR    Rr

r     Rr      rr

The generation has a genotypic ratio of 1 RR : 2 Rr : 1 rr. The phenotypic ratio is 3 round : 1 wrinkled.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
