Is this normal?

Hi, I am new to the forum and to growing tomatoes. I live in North Norfolk, UK. I have planted half a dozen Garden Pearl tomato seeds. All have germinated however, one seedling has 4 cotyledon leaves as opposed to two. Apart from the number of cotyledon leaves, the seedling looks identical to the others. Is this normal or should I discard the seedling as a mutation?

I have read some information about 3 leaf cotyledon seedlings but this is very limited and I have found nothing on 4 leaf varieties. Unfortunately I have been unable to access the FAQs so have not been able to check these.

Any help appreciated.
Thanks

Abstract
We describe mutations of three genes in Arabidopsis thaliana—extra
cotyledon1 (xtc1), extra cotyledon2 (xtc2), and altered meristem
programming1 (amp1)—that transform leaves into cotyledons. In all
three of these mutations, this transformation is associated with a
change in the timing of events in embryogenesis. xtc1 and xtc2 delay
the morphogenesis of the embryo proper at the globular-to-heart
transition but permit the shoot apex to develop to an unusually
advanced stage late in embryogenesis. Both mutations have little or no
effect on seed maturation and do not affect the viability of the shoot
or the rate of leaf initiation after germination. amp1 perturbs the
pattern of cell division at an early globular stage, dramatically
increases the size of the shoot apex and, like xtc1 and xtc2, produces
enlarged leaf primordia during seed development. These unusual
phenotypes suggest that these genes play important regulatory roles in
embryogenesis and demonstrate that the development of the shoot apical
meristem and the development of the embryo proper are regulated by
independent processes that must be temporally coordinated to ensure
normal organ identity.

Wow! From someone who still deals in degrees fahrenheit and inches of
rainfall, that explanation of what happens in 'mouse eared cress' would
confuse a university botanist. I will try to translate:-

In the germination of a seed, changes may take place in the number of
apparent cotyledons. This may involve the modification of one or two of the
first two true leaves to look like cotyledons. There will be no difference
in the look of the final plant. I am a well known breeder of Chrysanthemums
and each year amongst my seedlings there are 2-3% which have more than the
standard 2 cotyledons. In the past I have separated these in the hope that
these seedlings will in some ways be superior. I have found no such
superiority or flaws.

Grow your tomato seedlings on as normal, you will see no difference.

And I use feet and inches, lbs and oz, gallons and pints, and I wish
they would get rid of this new fangled money and bring back Pounds
shillings and pence.

Hi Dave and Phil,

Thank you both for your replies and your help (and for the translation). I will let the seedling live and grow it on with the others as suggested.

I'm with you on the lbs & ozs, gallons and pints, but I quite like the new money.

Best wishes

I remember when they got rid of the 1/2 p the outcry that now prices
would have to rise by 1p now.
Now when the supermarkets raise their prices, it seems to be 10p a
time.
